Under our old postfix setup, we standardized that addresses ending in -list were piped to our mailing list system. Since that resided on the same box as our MTA, we used two lines in transport_regexp that looked like this:
/^.*-list-(request|editor|subscribe|unsubscribe)\@domain\.co m$/ sympa:
Now that we're on zimbra, I'm running sympa on another box, so instead of using a different transport, I "just" need to forward those addresses to another box. I've tried adding the line:
canonical_maps = hash:/opt/zimbra/postfix/conf/canonical
to /opt/zimbra/postfix/conf/main.cf and then placing the following line in /opt/zimbra/postfix/conf/canonical:
So far, that seems to have no effect. Does anyone have any other suggestions for forwarding a matching set of addresses to another domain?
