+##################################################
+#          The Exim mail transport agent         #
+##################################################
+
+# This is the template for Exim's main build-time configuration file. It
+# contains settings that are independent of any operating system. These are
+# things that are mostly sysadmin choices. The items below are divided into
+# those you must specify, those you probably want to specify, those you might
+# often want to specify, and those that you almost never need to mention.
+
+# Edit this file and save the result to a file called Local/Makefile within the
+# Exim distribution directory before running the "make" command.
+
+# Things that depend on the operating system have default settings in
+# OS/Makefile-Default, but these are overridden for some OS by files called
+# called OS/Makefile-<osname>. You can further override these by creating files
+# called Local/Makefile-<osname>, where "<osname>" stands for the name of your
+# operating system - look at the names in the OS directory to see which names
+# are recognized.
+
+# However, if you are building Exim for a single OS only, you don't need to
+# worry about setting up Local/Makefile-<osname>. Any build-time configuration
+# settings you require can in fact be placed in the one file called
+# Local/Makefile. It is only if you are building for several OS from the same
+# source files that you need to worry about splitting off your own OS-dependent
+# settings into separate files. (There's more explanation about how this all
+# works in the toplevel README file, under "Modifying the building process", as
+# well as in the Exim specification.)
+
+# One OS-specific thing that may need to be changed is the command for running
+# the C compiler; the overall default is gcc, but some OS Makefiles specify cc.
+# You can override anything that is set by putting CC=whatever in your
+# Local/Makefile.
+
+# NOTE: You should never need to edit any of the distributed Makefiles; all
+# overriding can be done in your Local/Makefile(s). This will make it easier
+# for you when the next release comes along.
+
+# The location of the X11 libraries is something else that is quite variable
+# even between different versions of the same operating system (and indeed
+# there are different versions of X11 as well, of course). The four settings
+# concerned here are X11, XINCLUDE, XLFLAGS (linking flags) and X11_LD_LIB
+# (dynamic run-time library). You need not worry about X11 unless you want to
+# compile the Exim monitor utility. Exim itself does not use X11.
+
+# Another area of variability between systems is the type and location of the
+# DBM library package. Exim has support for ndbm, gdbm, tdb, and Berkeley DB.
+# By default the code assumes ndbm; this often works with gdbm or DB, provided
+# they are correctly installed, via their compatibility interfaces. However,
+# Exim can also be configured to use the native calls for Berkeley DB (obsolete
+# versions 1.85 and 2.x, or the current 3.x version) and also for gdbm.
+
+# For some operating systems, a default DBM library (other than ndbm) is
+# selected by a setting in the OS-specific Makefile. Most modern OS now have
+# a DBM library installed as standard, and in many cases this will be selected
+# for you by the OS-specific configuration. If Exim compiles without any
+# problems, you probably do not have to worry about the DBM library. If you
+# do want or need to change it, you should first read the discussion in the
+# file doc/dbm.discuss.txt, which also contains instructions for testing Exim's
+# interface to the DBM library.
+
+# In Local/Makefiles blank lines and lines starting with # are ignored. It is
+# also permitted to use the # character to add a comment to a setting, for
+# example
+#
+# EXIM_GID=42   # the "mail" group
+#
+# However, with some versions of "make" this works only if there is no white
+# space between the end of the setting and the #, so perhaps it is best
+# avoided. A consequence of this facility is that it is not possible to have
+# the # character present in any setting, but I can't think of any cases where
+# this would be wanted.

+
+# Exim will not build unless you specify BIN_DIRECTORY, CONFIGURE_FILE, and
+# EXIM_USER. You also need EXIM_GROUP if EXIM_USER specifies a uid by number.
+
+# If you don't specify SPOOL_DIRECTORY, Exim won't fail to build. However, it
+# really is a very good idea to specify it here rather than at run time. This
+# is particularly true if you let the logs go to their default location in the
+# spool directory, because it means that the location of the logs is known
+# before Exim has read the run time configuration file.
+
+#------------------------------------------------------------------------------
+# BIN_DIRECTORY defines where the exim binary will be installed by "make
+# install". The path is also used internally by Exim when it needs to re-invoke
+# itself, either to send an error message, or to recover root privilege. Exim's
+# utility binaries and scripts are also installed in this directory. There is
+# no "standard" place for the binary directory. Some people like to keep all
+# the Exim files under one directory such as /usr/exim; others just let the
+# Exim binaries go into an existing directory such as /usr/sbin or
+# /usr/local/sbin. The installation script will try to create this directory,
+# and any superior directories, if they do not exist.
+
+BIN_DIRECTORY=/usr/bin
+
+
+#------------------------------------------------------------------------------
+# CONFIGURE_FILE defines where Exim's run time configuration file is to be
+# found. It is the complete pathname for the file, not just a directory. The
+# location of all other run time files and directories can be changed in the
+# run time configuration file. There is a lot of variety in the choice of
+# location in different OS, and in the preferences of different sysadmins. Some
+# common locations are in /etc or /etc/mail or /usr/local/etc or
+# /usr/local/etc/mail. Another possibility is to keep all the Exim files under
+# a single directory such as /usr/exim. Whatever you choose, the installation
+# script will try to make the directory and any superior directories if they
+# don't exist. It will also install a default runtime configuration if this
+# file does not exist.
+
+CONFIGURE_FILE=/etc/mail/exim.conf
+
+# It is possible to specify a colon-separated list of files for CONFIGURE_FILE.
+# In this case, Exim will use the first of them that exists when it is run.
+# However, if a list is specified, the installation script no longer tries to
+# make superior directories or to install a default runtime configuration.
+
+
+#------------------------------------------------------------------------------
+# The Exim binary must normally be setuid root, so that it starts executing as
+# root, but (depending on the options with which it is called) it does not
+# always need to retain the root privilege. These settings define the user and
+# group that is used for Exim processes when they no longer need to be root. In
+# particular, this applies when receiving messages and when doing remote
+# deliveries. (Local deliveries run as various non-root users, typically as the
+# owner of a local mailbox.) Specifying these values as root is very strongly
+# discouraged. These values are compiled into the binary.
+
+EXIM_UID=79
+EXIM_GID=79
+
+# If the setting of EXIM_USER is numeric (e.g. EXIM_USER=42), there must
+# also be a setting of EXIM_GROUP. If, on the other hand, you use a name
+# for EXIM_USER (e.g. EXIM_USER=exim), you don't need to set EXIM_GROUP unless
+# you want to use a group other than the default group for the given user.
+
+# EXIM_GROUP=
+
+# Many sites define a user called "exim", with an appropriate default group,
+# and use
+#
+# EXIM_USER=exim
+#
+# while leaving EXIM_GROUP unspecified (commented out).
+
+
+#------------------------------------------------------------------------------
+# SPOOL_DIRECTORY defines the directory where all the data for messages in
+# transit is kept. It is strongly recommended that you define it here, though
+# it is possible to leave this till the run time configuration.
+
+# Exim creates the spool directory if it does not exist. The owner and group
+# will be those defined by EXIM_USER and EXIM_GROUP, and this also applies to
+# all the files and directories that are created in the spool directory.
+
+# Almost all installations choose this:
+
+SPOOL_DIRECTORY=/var/spool/exim

+#------------------------------------------------------------------------------
+# These settings determine which individual router drivers are included in the

+# If you have set LOOKUP_LDAP=yes, you should set LDAP_LIB_TYPE to indicate

+# The items in this section are those that are commonly changed according to
+# the sysadmin's preferences, but whose defaults are often acceptable.
+
+
+#------------------------------------------------------------------------------
+# Exim has support for the AUTH (authentication) extension of the SMTP
+# protocol, as defined by RFC 2554. If you don't know what SMTP authentication
+# is, you probably won't want to include this code, so you should leave these
+# settings commented out. If you do want to make use of SMTP authentication,
+# you must uncomment at least one of the following, so that appropriate code is
+# included in the Exim binary. You will then need to set up the run time
+# configuration to make use of the mechanism(s) selected.
+
+AUTH_CRAM_MD5=yes
+AUTH_PLAINTEXT=yes
+# AUTH_SPA=yes
+
+
+#------------------------------------------------------------------------------
+# The passwords for user accounts are normally encrypted with the crypt()
+# function. Comparisons with encrypted passwords can be done using Exim's
+# "crypteq" expansion operator. (This is commonly used as part of the
+# configuration of an authenticator for use with SMTP AUTH.) At least one
+# operating system has an extended function called crypt16(), which uses up to
+# 16 characters of a password (the normal crypt() uses only the first 8). Exim
+# supports the use of crypt16() as well as crypt().
+
+# You can always indicate a crypt16-encrypted password by preceding it with
+# "{crypt16}". If you want the default handling (without any preceding
+# indicator) to use crypt16(), uncomment the following line:
+
+# DEFAULT_CRYPT=crypt16
+
+# If you do that, you can still access the basic crypt() function by preceding
+# an encrypted password with "{crypt}". For more details, see the description
+# of the "crypteq" condition in the manual chapter on string expansions.
+
+# Since most operating systems do not include a crypt16() function (yet?), Exim
+# has one of its own, which it uses unless HAVE_CRYPT16 is defined. Normally,
+# that will be set in an OS-specific Makefile for the OS that have such a
+# function, so you should not need to bother with it.
+
+
+#------------------------------------------------------------------------------
+# Exim can be built to support the SMTP STARTTLS command, which implements
+# Transport Layer Security using SSL (Secure Sockets Layer). To do this, you
+# must install the OpenSSL library package or the GnuTLS library. Exim contains
+# no cryptographic code of its own. Uncomment the following lines if you want
+# to build Exim with TLS support. If you don't know what this is all about,
+# leave these settings commented out.
+
+# This setting is required for any TLS support (either OpenSSL or GnuTLS)
+SUPPORT_TLS=yes
+
+# Uncomment this setting if you are using OpenSSL
+TLS_LIBS=-lssl -lcrypto
+
+# Uncomment these settings if you are using GnuTLS
+# USE_GNUTLS=yes
+# TLS_LIBS=-lgnutls -ltasn1 -lgcrypt
+
+# If you are running Exim as a server, note that just building it with TLS
+# support is not all you need to do. You also need to set up a suitable
+# certificate, and tell Exim about it by means of the tls_certificate
+# and tls_privatekey run time options. You also need to set tls_advertise_hosts
+# to specify the hosts to which Exim advertises TLS support. On the other hand,
+# if you are running Exim only as a client, building it with TLS support
+# is all you need to do.
+
+# Additional libraries and include files are required for both OpenSSL and
+# GnuTLS. The TLS_LIBS settings above assume that the libraries are installed
+# with all your other libraries. If they are in a special directory, you may
+# need something like
+
+# TLS_LIBS=-L/usr/local/openssl/lib -lssl -lcrypto
+# or
+# TLS_LIBS=-L/opt/gnu/lib -lgnutls -ltasn1 -lgcrypt
+
+# TLS_LIBS is included only on the command for linking Exim itself, not on any
+# auxiliary programs. If the include files are not in a standard place, you can
+# set TLS_INCLUDE to specify where they are, for example:
+
+# TLS_INCLUDE=-I/usr/local/openssl/include/
+# or
+# TLS_INCLUDE=-I/opt/gnu/include
+
+# You don't need to set TLS_INCLUDE if the relevant directories are already
+# specified in INCLUDE.
+
+
+#------------------------------------------------------------------------------
+# The default distribution of Exim contains only the plain text form of the
+# documentation. Other forms are available separately. If you want to install
+# the documentation in "info" format, first fetch the Texinfo documentation
+# sources from the ftp directory and unpack them, which should create files
+# with the extension "texinfo" in the doc directory. You may find that the
+# version number of the texinfo files is different to your Exim version number,
+# because the main documentation isn't updated as often as the code. For
+# example, if you have Exim version 4.03, the source tarball upacks into a
+# directory called exim-4.03, but the texinfo tarball unpacks into exim-4.00.
+# In this case, move the contents of exim-4.00/doc into exim-4.03/doc after you
+# have unpacked them. Then set INFO_DIRECTORY to the location of your info
+# directory. This varies from system to system, but is often /usr/share/info.
+# Once you have done this, "make install" will build the info files and
+# install them in the directory you have defined.
+
+INFO_DIRECTORY=/usr/share/info
+
+
+#------------------------------------------------------------------------------
+# Exim log directory and files: Exim creates several log files inside a
+# single log directory. You can define the directory and the form of the
+# log file name here. If you do not set anything, Exim creates a directory
+# called "log" inside its spool directory (see SPOOL_DIRECTORY above) and uses
+# the filenames "mainlog", "paniclog", and "rejectlog". If you want to change
+# this, you can set LOG_FILE_PATH to a path name containing one occurrence of
+# %s. This will be replaced by one of the strings "main", "panic", or "reject"
+# to form the final file names. Some installations may want something like this:
+
+LOG_FILE_PATH=/var/log/exim/%s.log
+
+# which results in files with names /var/log/exim_mainlog, etc. The directory
+# in which the log files are placed must exist; Exim does not try to create
+# it for itself. It is also your responsibility to ensure that Exim is capable
+# of writing files using this path name. The Exim user (see EXIM_USER above)
+# must be able to create and update files in the directory you have specified.
+
+# You can also configure Exim to use syslog, instead of or as well as log
+# files, by settings such as these
+
+# LOG_FILE_PATH=syslog
+# LOG_FILE_PATH=syslog:/var/log/exim_%slog
+
+# The first of these uses only syslog; the second uses syslog and also writes
+# to log files. Do not include white space in such a setting as it messes up
+# the building process.
+
+
+#------------------------------------------------------------------------------
+# When logging to syslog, the following option caters for syslog replacements
+# that are able to accept log entries longer than the 1024 characters allowed
+# by RFC 3164. It is up to you to make sure your syslog daemon can handle this.
+# Non-printable characters are usually unacceptable regardless, so log entries
+# are still split on newline characters.
+
+# SYSLOG_LONG_LINES=yes
+
+# If you are not interested in the process identifier (pid) of the Exim that is
+# making the call to syslog, then comment out the following line.
+
+SYSLOG_LOG_PID=yes
+
+
+#------------------------------------------------------------------------------
+# Cycling log files: this variable specifies the maximum number of old
+# log files that are kept by the exicyclog log-cycling script. You don't have
+# to use exicyclog. If your operating system has other ways of cycling log
+# files, you can use them instead. The exicyclog script isn't run by default;
+# you have to set up a cron job for it if you want it.
+
+EXICYCLOG_MAX=10
+
+
+#------------------------------------------------------------------------------
+# The compress command is used by the exicyclog script to compress old log
+# files. Both the name of the command and the suffix that it adds to files

+# Compiling in support for embedded Perl: If you want to be able to
+# use Perl code in Exim's string manipulation language and you have Perl

+# Another default action of the install script is to install a default runtime
+# configuration file if one does not exist. This configuration has a router for
+# expanding system aliases. The default assumes that these aliases are kept
+# in the traditional file called /etc/aliases. If such a file does not exist,
+# the installation script creates one that contains just comments (no actual
+# aliases). The following setting can be changed to specify a different
+# location for the system alias file.
+
+SYSTEM_ALIASES_FILE=/etc/aliases

+#------------------------------------------------------------------------------
+# The following commands live in different places in some OS. Either the
+# ultimate default settings, or the OS-specific files should already point to
+# the right place, but they can be overridden here if necessary. These settings
+# are used when building various scripts to ensure that the correct paths are
+# used when the scripts are run. They are not used in the Makefile itself. Perl
+# is not necessary for running Exim unless you set EXIM_PERL (see above) to get
+# it embedded, but there are some utilities that are Perl scripts. If you
+# haven't got Perl, Exim will still build and run; you just won't be able to
+# use those utilities.
+
+# CHOWN_COMMAND=/usr/bin/chown
+# CHGRP_COMMAND=/usr/bin/chgrp
+# MV_COMMAND=/bin/mv
+# RM_COMMAND=/bin/rm
+# PERL_COMMAND=/usr/bin/perl
+
+
+#------------------------------------------------------------------------------
+# The following macro can be used to change the command for building a library
+# of functions. By default the "ar" command is used, with options "cq".
+# Only in rare circumstances should you need to change this.
+
+# AR=ar cq
+
+
+#------------------------------------------------------------------------------
+# The following macros can be used to change the default modes that are used
+# by the appendfile transport. In most installations the defaults are just
+# fine, and in any case, you can change particular instances of the transport
+# at run time if you want.
+
+# APPENDFILE_MODE=0600
+# APPENDFILE_DIRECTORY_MODE=0700
+# APPENDFILE_LOCKFILE_MODE=0600
+
+
+#------------------------------------------------------------------------------
+# In some installations there may be multiple machines sharing file systems,
+# where a different configuration file is required for Exim on the different
+# machines. If CONFIGURE_FILE_USE_NODE is defined, then Exim will first look
+# for a configuration file whose name is that defined by CONFIGURE_FILE,
+# with the node name obtained by uname() tacked on the end, separated by a
+# period (for example, /usr/exim/configure.host.in.some.domain). If this file
+# does not exist, then the bare configuration file name is tried.
+
+CONFIGURE_FILE_USE_NODE=yes
+
+
+#------------------------------------------------------------------------------
+# In some esoteric configurations two different versions of Exim are run,
+# with different setuid values, and different configuration files are required
+# to handle the different cases. If CONFIGURE_FILE_USE_EUID is defined, then
+# Exim will first look for a configuration file whose name is that defined
+# by CONFIGURE_FILE, with the effective uid tacked on the end, separated by
+# a period (for eximple, /usr/exim/configure.0). If this file does not exist,
+# then the bare configuration file name is tried. In the case when both
+# CONFIGURE_FILE_USE_EUID and CONFIGURE_FILE_USE_NODE are set, four files
+# are tried: <name>.<euid>.<node>, <name>.<node>, <name>.<euid>, and <name>.
+
+# CONFIGURE_FILE_USE_EUID=yes
+
+
+#------------------------------------------------------------------------------
+# The size of the delivery buffers: These specify the sizes (in bytes) of
+# the buffers that are used when copying a message from the spool to a
+# destination. There is rarely any need to change these values.
+
+# DELIVER_IN_BUFFER_SIZE=8192
+# DELIVER_OUT_BUFFER_SIZE=8192
+
+
+#------------------------------------------------------------------------------
+# The mode of the database directory: Exim creates a directory called "db"
+# in its spool directory, to hold its databases of hints. This variable
+# determines the mode of the created directory. The default value in the
+# source is 0750.
+
+# EXIMDB_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# Database file mode: The mode of files created in the "db" directory defaults
+# to 0640 in the source, and can be changed here.
+
+# EXIMDB_MODE=0640
+
+
+#------------------------------------------------------------------------------
+# Database lock file mode: The mode of zero-length files created in the "db"
+# directory to use for locking purposes defaults to 0640 in the source, and
+# can be changed here.
+
+# EXIMDB_LOCKFILE_MODE=0640
+
+
+#------------------------------------------------------------------------------
+# This parameter sets the maximum length of the header portion of a message
+# that Exim is prepared to process. The default setting is one megabyte. The
+# limit exists in order to catch rogue mailers that might connect to your SMTP
+# port, start off a header line, and then just pump junk at it for ever. The
+# message_size_limit option would also catch this, but it may not be set.
+# The value set here is the default; it can be changed at runtime.
+
+# HEADER_MAXSIZE="(1024*1024)"
+
+
+#------------------------------------------------------------------------------
+# The mode of the input directory: The input directory is where messages are
+# kept while awaiting delivery. Exim creates it if necessary, using a mode
+# which can be defined here (default 0750).
+
+# INPUT_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# The mode of Exim's log directory, when it is created by Exim inside the spool
+# directory, defaults to 0750 but can be changed here.
+
+# LOG_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# The log files themselves are created as required, with a mode that defaults
+# to 0640, but which can be changed here.
+
+# LOG_MODE=0640
+
+
+#------------------------------------------------------------------------------
+# The TESTDB lookup is for performing tests on the handling of lookup results,
+# and is not useful for general running. It should be included only when
+# debugging the code of Exim.
+
+# LOOKUP_TESTDB=yes
+
+
+#------------------------------------------------------------------------------
+# /bin/sh is used by default as the shell in which to run commands that are
+# defined in the makefiles. This can be changed if necessary, by uncommenting
+# this line and specifying another shell, but note that a Bourne-compatible
+# shell is expected.
+
+# MAKE_SHELL=/bin/sh
+
+
+#------------------------------------------------------------------------------
+# The maximum number of named lists of each type (address, domain, host, and
+# local part) can be increased by changing this value. It should be set to
+# a multiple of 16.
+
+# MAX_NAMED_LIST=16
+
+
+#------------------------------------------------------------------------------
+# Network interfaces: Unless you set the local_interfaces option in the runtime
+# configuration file to restrict Exim to certain interfaces only, it will run
+# code to find all the interfaces there are on your host. Unfortunately,
+# the call to the OS that does this requires a buffer large enough to hold
+# data for all the interfaces - it was designed in the days when a host rarely
+# had more than three or four interfaces. Nowadays hosts can have very many
+# virtual interfaces running on the same hardware. If you have more than 250
+# virtual interfaces, you will need to uncomment this setting and increase the
+# value.
+
+# MAXINTERFACES=250
+
+
+#------------------------------------------------------------------------------
+# Per-message logs: While a message is in the process of being delivered,
+# comments on its progress are written to a message log, for the benefit of
+# human administrators. These logs are held in a directory called "msglog"
+# in the spool directory. Its mode defaults to 0750, but can be changed here.
+# The message log directory is also used for storing files that are used by
+# transports for returning data to a message's sender (see the "return_output"
+# option for transports).
+
+# MSGLOG_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# There are three options which are used when compiling the Perl interface and
+# when linking with Perl. The default values for these are placed automatically
+# at the head of the Makefile by the script which builds it. However, if you
+# want to override them, you can do so here.
+
+# PERL_CC=
+# PERL_CCOPTS=
+# PERL_LIBS=
+
+
+#------------------------------------------------------------------------------
+# Identifying the daemon: When an Exim daemon starts up, it writes its pid
+# (process id) to a file so that it can easily be identified. The path of the
+# file can be specified here. Some installations may want something like this:
+
+PID_FILE_PATH=/var/run/exim%s.pid
+
+# If PID_FILE_PATH is not defined, Exim writes a file in its spool directory
+# using the name "exim-daemon.pid".
+
+# If you start up a daemon without the -bd option (for example, with just
+# the -q15m option), a pid file is not written. Also, if you override the
+# configuration file with the -oX option, no pid file is written. In other
+# words, the pid file is written only for a "standard" daemon.
+
+
+#------------------------------------------------------------------------------
+# If Exim creates the spool directory, it is given this mode, defaulting in the
+# source to 0750.
+
+# SPOOL_DIRECTORY_MODE=0750
+
+
+#------------------------------------------------------------------------------
+# The mode of files on the input spool which hold the contents of messages can
+# be changed here. The default is 0640 so that information from the spool is
+# available to anyone who is a member of the Exim group.
+
+SPOOL_MODE=0640
+
+
+#------------------------------------------------------------------------------
+# Moving frozen messages: If the following is uncommented, Exim is compiled
+# with support for automatically moving frozen messages out of the main spool
+# directory, a facility that is found useful by some large installations. A
+# run time option is required to cause the moving actually to occur. Such
+# messages become "invisible" to the normal management tools.
+
+# SUPPORT_MOVE_FROZEN_MESSAGES=yes
+
