Thanks again Mark. I've decided to manage it with separate postfix config files (one for when there is no service group on a server, one for when there is just the Mailman service group, one for when there is just the IMAP service group and one when there is both) and just restart postfix and monitor it as part of VCS as it doesn't make sense to merge config files for other reasons anyway.

Regards, Troy

For some reason when I moved the mailman configuration a few months ago

I had to add /etc/mailman/aliases to the alias_maps e.g.,:

alias_maps = hash:/etc/aliases

           hash:/etc/mailman/aliases

whereas on the old installation I didn't. Since this is on a server that can fail over to another server that has the IMAP configuration which

doesn't need /etc/mailman/aliases I would like to see if there is a workaround so that they both have the same postfix configuration.
Sorry

if this is more of a postfix question but I didn't get an answer on their list yet.

Postfix doesn't do IMAP, nor do other MTAs, so I'm not sure if the IMAP reference is relevant.

Is the Mailman package on the other server the same as the one on this server which is clearly a downstream package if aliases are in /etc/mailman.

Basically trying to get the /etc/postfix/main.cf files identical so I don't have to manage the differences and bounce postfix on failover.

If Mailman is installed the same way from the same package on both servers, and there are no non-mailman differences in the Postfix configuration, there should be no reason why they couldn't use the same main.cf.

On the other hand if the two servers have different Mailman packages, then their Postfix requirements could be different.

On the third hand, this could be simply that on the other server, Mailman's aliases were copied to /etc/aliases so /etc/mailman/aliases wasn't needed.
