+Subject: [EXIM] gadget to parse log file and generate bounce message
+
+These steps can process exim log files, and generate a bounce message
+back to mailing lists, thus clearing the bad address off the list.
+
+Bounce message come in a couple of flavors. First of all, it could
+bounce before the message even got there. They just reply with an
+SMTP code of 5xx, such as 550 - User Unknown. Juno.com does it this
+way.
+
+Or they could accept the message, and then later on realize that the
+user is unknown, and email back a bounce message. Aol.com does it
+like this.
+
+This gadget will help remove bad addresses from juno.com, and similiar
+mail hosts. Since there is no bounce message, the information must be
+gotten from the exim log (typically called exim_mainlog).
+
+This works ok with the Smartlist Mailing List Manager.
+
+
+4 Steps
+
+1) Use Eximstats to generate error only report, and mail to special
+procmail recipe.
+
+ Put this in your crontab file
+
+ 54 23 * * * root /usr/local/exim/bin/eximstats -nt -h0 -q0
+-nr -t0 /var/log/exim/exim_mainlog 2>&1 | /bin/mail -s 'exim errors' bouncer
+
+
+
+ It generates a report like this
+
+ 1 Joe@aol.net <jokes@mail.domain.com>: unrouteable mail
+domain "aol.net"
+
+which means that the error occured 1 time, joe@aol.net was the mailing
+list subscriber, and jokes was the mailing list.
+
+2) Procmail recipe massages headers, and passes body of message to
+Perl program. Handle email sent to bouncer address.

+ # This program will generate bounce messages, and send them to the
+ # appropriate list-request address.
+ #
+ # This program is invoked by a Procmail recipe. The body of the email
+ # message is an error report produced by Eximstats.
+ #
+ # The error report has a specific format of error messages, which
+looks like
+ #
+ # 1 u2pino@telcel.net.ve <chistes@mail.domain.com>
+ #
+ # From which the first email address is the bad address, and the
+second
+ # address is the list address. Which can easily be transformed into
+ # the list-request address.
+ #
+ # This program uses the Perl Module Mail::Internet to send each
+message.
+ #
+ #
+ #
+
+ use Mail::Internet;
+
+ chop(my $Date = `date "+%Y-%m-%d %T"`);
+
+ my $error_ind = ' \d '; # all error lines start
+with this sequence
+ my $bounce_body = ' 550 '; # 550 is SMTP error code for user
+unknown
+ open(LOG,">>/tmp/bouncer.log") || die(" Could not open bouncer.log
+$!");
+
+ $ENV{'SMTPHOSTS'} = 'localhost';
+
+ my $mesg = new Mail::Internet \*STDIN;
+
+ # look at mail headers, and grab the data
+
+ my $from = $mesg->head->get('From'); chop($from);
+ my $subject = $mesg->head->get('Subject'); chop($subject);
+
+ # tidy up the body
+
+ my $body = $mesg->body();
+ map {chop($_)} @$body;
+
+ # @commands is an array of each line in the message body.
+
+ my @commands = @$body;
+
+ @$body = ();
+
+ my $command;
+ foreach $command (@commands) {
+
+ next if $command =~ m/^\s*$/; # skip
+blank lines
+
+ unless ($command =~ m/^$error_ind/) {
+ next;
+ }
+
+ @tokens = split(/\s+/, $command); # put each word
+into a seperate array cell
+
+ my $bad_address = $tokens[2]; # bad
+address that caused the list problems
+
+ my $list_address = $tokens[3]; # list address that
+had problems
+
+ $list_address =~ s/<//; #
+strip < symbol from address
+ $list_address =~ s/>//; #
+strip > symbol from address
+ $list_address =~ s/://; #
+strip colon symbol from address
+ $list_address =~ s/\@/-request\@/; # add request onto
+user name
+
+ unless ($bad_address =~ m/\@/) {
+ next;
+ }
+
+ unless ($list_address =~ m/\@/) {
+ next;
+ }
+
+ # make the body of the message a simple bounce message that
+smartlist can handle
+
+ my $message_body = $bounce_body . "<" . $bad_address . ">"
+. "\n";
+
+ my $new_mesg = new Mail::Internet(
+ [ ],
+ 'Body' => [$message_body]
+ );
+
+ # this is who the mail is directed to via SMTP;
+
+ $ENV{MAILADDRESS} = $from;
+
+ # these are the addresses placed in the header block of the
+message.
+
+ $new_mesg->head()->add('From', $from);
+ $new_mesg->head()->add('To', $list_address);
+ $new_mesg->head()->add('Subject', $subject);
+
+ # $new_mesg->print_header(\*LOG);
+ # $new_mesg->print_body(\*LOG);
+
+ print LOG "$Date\t$list_address\t$bad_address\n";
+
+ my @recips = $new_mesg->smtpsend;
+
+ unless (@recips > 0) {
+ print LOG "Failed to deliver
+($from,$list_address,$message_body) \n";
+ next;
+ }
+
+ }
+
+
+4) Mailing list software unsubscribes bad address.
+
+
+
+Assumes
+
+You have Procmail installed. Preferably the latest version.
+
+Your exim configuration file receives incoming mail for localhost ip
+address. For example,
+
+ local_domains = "@:domain.com:[127.0.0.1]"
+
+You have Eximstats, which is a Perl program to report on the exim
+mainlog, that comes with Exim as standard equipment.
+
+You have the Perl Mailtools modules installed. This module takes care
+of sending via SMTP interchange a mail message to the list request
+address.
+
+I will be happy to take corrections, updates, or additions via private
+email (mdm@internet-tools.com).
