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> <h4>The above tip works with Mailman 2.0; Mailman 2.1 has adopted something very similar so that no workaround is necessary. See the README.POSTFIX file included with Mailman-2.1.<br> </h4> <br> <br> <br> </body> </html>
