<h4><!--mstheme--><font face="times new roman, Times New Roman, Times" color="#666666">The following was posted on the Postfix mailing list on 5/4/2002 by Michael
Tokarev as a suggested addition to the Postfix FAQ.<!--mstheme--></font></h4>
<p>Q: Mailman does not work with Postfix, complaining about GID mismatch<br>
<br>
A: Mailman uses a setgid wrapper that is designed to be used in system-wide
aliases file so that rest of mailman's mail handling processes will run with
proper uid/gid. Postfix has an ability to run a command specified in an alias as
owner of that alias, thus mailman's wrapper is not needed here. The best method
to invoke mailman's mail handling via aliases is to use separate alias file
especially for mailman, and made it owned by mailman and group mailman. Like:<br>
<br>
alias_maps = hash:/etc/postfix/aliases, hash:/var/mailman/aliases<br>
<br>
Make sure that /var/mailman/aliases.db is owned by mailman user (this may be
done by executing postalias as mailman userid).<br>
<br>
Next, instead of using mailman-suggested aliases entries with wrapper, use the
following:<br>
<br>
instead of<br>
mailinglist: /var/mailman/mail/wrapper post mailinglist<br>
mailinglist-admin: /var/mailman/mail/wrapper mailowner mailinglist<br>
mailinglist-request: /var/mailman/mail/wrapper mailcmd mailinglist<br>
...<br>
<br>
use<br>
mailinglist: /var/mailman/scripts/post mailinglist<br>
mailinglist-admin: /var/mailman/scripts/mailowner mailinglist<br>
mailinglist-request: /var/mailman/scripts/mailcmd mailinglist<br>
...</p>
