Hi there Postfix lovers!
 
One _very_ good software for administration of users and domains in a
postfix world is Postfix Admin by Mischa Peters. Look at
http://high5.net/postfixadmin
 
It stores everything in MySQL ... even the vacation messages.
 
I don't know how well it works an a server with postfix + postfix admin +
mailscanner since my setup is a three layer setup but I think it will
work.
 
Cheers,
Jonas Back

Ämne: Postfix & Virtual Users Auto Responder

Hello Folks.

I have managed to get a working auto response system working for
MailScanner users running Postfix with MySQL based virtual users. 

I may be slightly off topic with this post, but auto responders are
difficult to come by for this virtual setup.  Julian,  I hope you
don't mind me posting here to help our Postfix users. :)

Here we go, with some formatting to make this readable.

________________________________________________________________________

--- Description ---
I pieced together a system of old fixes, modified code, and put
together a semi-simple way to use auto responders with MailScanner,
Postfix, and Virtual Users.  You will need to make a few database
entrees and create a text file to use this system.

--- Instructions ---
1.  This perl script can be run from anywhere, but I chose to place
it in my virtual mail directory. (/home/vmail/)  I have set the
ownership to my vmail user.

--- autoreply code start ----

#!/usr/bin/perl -w
#
# Filename: autoreply
# Updated By: Wess Bechard <wess at eliquid.com>
# Author: David Miller <dmillernewportnet.com>, based on a
# script posted to the postfix-users maillist by
# Gimbert Mario <mgimbertsbsd.de> on 02 Dec 2002.
#
#
use strict;
package main;
# location of sendmail binary
my $SENDMAIL = "/usr/sbin/sendmail";

#----------------------------
# Main Thread of Execution
#----------------------------
#my ($sender, $reciplist) = $ARGV;
my ($sender, $reciplist) = @ARGV;
# do not reply to mailing lists
exit 0 if($sender=~/^(?i)owner-.*|^(?i)newsletter.*|(?i)listserver.*|^(?i)mailerdaemon.*
^(?i)mailer-daemon.*/);

# break apart recipient list
$reciplist=~s/,/ /g;
#print "$reciplist\n";
my @recips = split(" ", $reciplist);

# check each recipient and send mail
foreach my $rec (@recips) {
         my ($user, $domain) = split("@", $rec);
         $domain =~ s/autoreply\.//;
         my $file = "/home/vmail/$domain/$user/autoreply.txt";
#        print "$file\n";
         if( -f $file) {
        #        print "$file\n";
                 sendreplyto($sender, "$user\@$domain", $file);
         }
}

exit 0;

sub sendreplyto
{
         my ($sender, $recip, $replyfile);
         ($sender, $recip, $replyfile) = @_;
         #print "$replyfile";
         open(MAIL, "|$SENDMAIL -f '' -t") ||
                 die "Cannot execute $SENDMAIL: $!\n";
         print MAIL <<EOF;
From: $recip (Automatic reply service)
To: $sender
Subject: $recip is away from the mail
EOF
         # send contents of reply file
         open(REPLY, "<$replyfile") ||
                 die "Cannot open file $replyfile $!\n";
         while(<REPLY>) {
                 print MAIL $_;
         }
         print MAIL "\n";
         close REPLY || die "Close of $replyfile failed: $!\n";
         close MAIL || die "$SENDMAIL failed: $!\n";
}

--- autoreply code end ----


2.  Add the following transport to the end of your
/etc/postfix/master.cf.

autoreply unix  -       n       n       -       -       pipe
  flags=F user=vmail argv=/home/vmail/autoreply $sender $recipient

Please change the user to match the permissions set to the perl
script.


3.  Please add the following data to the transport table if it does
not exist.
This step will need to be done once for every domain using auto
responders.

In Transport table:
Domain:  autoreply.domain.tld
Destination:  autoreply

4.  Create a forward for the user that uses the new autoreply
transport.

In Virtual table:
Create a forward to the user's usual inbox first.
Email: user at domain.tld
Destination: user at domain.tld

Now create a forward to the autoreply.
Email: user at domain.tld
Destination: user at autoreply.domain.tld

5.  Create the autoreply.txt in the user's maildir.

/home/vmail/domain.tld/user/autoreply.txt

Adjust directory path to taste.
The autoreply.txt can contain any plain text email message.
