1 Introduction: What is Exim?

Exim is an SMTP (Simple Mail Transfer Protocol) Server for UNIX. Exim is a replacment for Sendmail. Exim is vastly improved over Sendmail in many ways. The most notable is ease configuration.

2 Configuring Exim for @Mail

If Exim is not currently installed, download and uncompress the tar file. Make sure to edit the Local/Makefile and declare your Spool directory and all your needed options.

Open the /usr/exim/configure file.

If the main configuration section:

Change the variable declarations to match your system as described on the file. Make sure that you add your domains to /etc/localdomains

At the bottom of the main configuration section, add the following.


# Change your webserver username
trusted_users = nobody

ATMAIL_HOME = /usr/local/atmail/
ATMAIL_SAVEEMAIL = /www/atmail3/saveemail.pl
ATMAIL_UID = nobody
ATMAIL_GID = nobody

In the Transports configuration section, add the following:

atmail:
  driver = pipe
  command = ATMAIL_SAVEEMAIL ${lc:$local_part}@$domain
  current_directory = ATMAIL_HOME
  home_directory = ATMAIL_HOME
  user = ATMAIL_UID
  group = ATMAIL_GID

At the top of the Directors section, add the following.:

all:
  driver = smartuser
  transport = atmail

If you are running the @Mail POP3 server and want to use the POP before SMTP method to add accepted relay domains to your allowed hosts, add the following line to your Exim configuration. See the POP3 section of the docs for more information on running the @Mail POP3 Server

  host_accept_relay = localhost : hostname : /usr/exim/relay-access

2.1 Verify the configure file and Start / Restart Exim.

Verify the configure file.
root# /usr/exim/bin/exim -C /usr/exim/configure -bV

You should receive similar to:

Exim version 3.32 #4 built 27-Feb-2002 07:38:43
Copyright (c) University of Cambridge 2001

If you recieve any errors, check your syntax in the configure file.

root# killall -HUP exim

or, if exim is not running:

root# /usr/exim/bin/exim -d2 -bd -q30m

Now open @Mail in your webbrower, go to the webadmin and configure the sendmail binary for exim. (using the command above, without '-d2' for debugging)

root# tail -f /var/spool/exim/log/mainlog

To see if there are any errors.

2.2 How @Mail receives emails

By configuring the exim with a new rule, all emails to the destination hostname are sent to the @Mail saveemail.pl script for delivery.

The saveemail.pl script receives the recipient of the email via the command line , the headers and body of the message are sent via STDIN.
