<p>Mailman is a list manager with web front end and built in
archiving functions. Details can be found at <a href="http://www.list.org/">http://www.list.org/</a></p>
<h2>Mailman configuration</h2>
- <p>There is no mailman configuration needed other than the
- standard options detailed in the mailman install documentation.
- The exim configuration is transparent to mailman. The uid/gid
- settings for mailman must match those in the config fragments

<h2>Exim configuration</h2>
<p>The exim configuration is built so that a list created within

<p>The drawback of this configuration is that it will work poorly
on systems supporting lists in several different mail domains -

now. This may change in the future</p>
<p>The configuration file segments included are to be built on top
configuration, with entries (within the list domain) for
<tt>mailman</tt>, <tt>mailman-request</tt> and
<tt>mailman-admin</tt> (plus any other global contact addresses
- for the list master.</p>

+ necessarily the same for all of these aliases) human rather than
+ being piped into Mailman. You do <b>not</b> need to put per-list
+ entries into the system alias file, and doing so will most likely
+ break things since the user id used for delivery is likely to be
+ incorrect or not set (which causes an exim delivery time config
+ error).</p>
<p>There are 3 config file sections below which need pasting into
the appropriate parts of the main exim config file. The first one

<h4>Main config file section</h4>
<pre>
## Tailor these to fit your installation
## pretty much everything else should just fit...

<li>Mailman's detection of exim bounces needs improving - it really
should make use of the extra header information that exim provides.
It also should recognise and deal with or ignore delay warning
- messages.</li>

+ but still passes delay warnings to the list administrator</i></li>
<li>List existence is checked on whether there is a config.db file
for a list. If you delete lists by foul means, be aware of
this.</li>
+
+ <li>If you are getting exim or Mailman complaining about user ids
+ when you send mail to a list, check that the MAILMAN_UID and
+ MAILMAN_GID match those of Mailman itself. Also make sure you do
+ <b>not</b> have aliases in the main alias file for the list.</li>
</ul>
<h2>Other Tweaks</h2>
<p>One solution passed to me for handling virtual domains was -

+ <h2>Exim List Efficiency Tweaks</h2>
+
+ <p>This is a set of configuration directives I used on the list
+ boxes I admin. Some of these are necessary, others are cosmetic,
+ a few are probably superfluous - they work for me!</p>
+<pre>
+# definition of injecting IP addresses
+LOCAL_NETS=127.0.0.1/32
+#
+# Extra logging data - not necessary but makes the logs more
+# useful, but bigger
+# lookup all hostnames - puts hostnames into log as well as ips
+host_lookup = 0.0.0.0/0
+# tweak logging
+log_all_parents
+log_file_path = /var/log/exim/%s.log
+log_received_recipients
+log_refused_recipients
+log_received_sender
+log_smtp_confirmation
+#
+# RBL settings - these are more severe than I use
+rbl_domains = rbl.maps.vix.com/reject:relays.mail-abuse.org/reject:dul.maps.vix.com/reject:relays.orbs.org=127.0.0.2,127.0.0.3/reject
+rbl_hosts = !LOCAL_NETS:0.0.0.0/0
+rbl_log_rcpt_count
+recipients_reject_except=postmaster@*:*-admin@*
+#
+# relay control - from our local network only
+host_accept_relay = LOCAL_NETS
+#
+# delay warnings - second line is now default, but earlier versions of
+# exim need it setting
+delay_warning = 26h
+##delay_warning_condition = "${if match{$h_precedence:}{(?i)bulk|list|junk}{no}{yes}}"
+#
+# Verify receipient addresses on everything except local injects
+# DO NOT verify addresses from Mailman - this would slow down
+# the acceptance of messages dramatically
+receiver_verify_hosts = !127.0.0.1/8:0.0.0.0/0
+sender_verify
+#
+# performance tweaks - 1st is good for linux, maybe less so for others
+split_spool_directory
+remote_max_parallel = 15
+</pre>
+
+<h2>List verification</h2>
+
+<p>This is how a set of address tests for the exim lists look on a
+working system. (command lines start with ">")</p>
+<pre>
