Thanks, Mark.

I (finally) started working on this ... and in trying to implement your 
suggestion — ran into a problem, I think.

The current postfix_vmap has entries like:

list-boun...@lists.domain.info                lmtp:[mailman-core]:24

This looks very strange. It should be something like
```
list-boun...@lists.domain.info   list-bounces@alias.domain
```
where alias.domain is the configured alias domain for the mail host lists.domain.info.


So, when I try adding entries to a separate vmap file, like:

list-boun...@lists.domain.info                lmtp:[mailman-core]:24, 
u...@gmail.com

It only goes through normal bounce processing.

If I do:

list-boun...@lists.domain.info                u...@gmail.com, 
lmtp:[mailman-core]:24

Then it goes to the gmail address, and no bounce processing happens.

The issue here is the value `lmtp:[mailman-core]:24` is completely wrong. It should be an email address with a syntactically valid domain name. The domain name isn't a real domain. It is only a name exposed to Postorius in the postfix_vmap and postfix_lmtp files.

What do you have configured for the alias domain for the lists.domain.info domain? See https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html#unusual-postfix-configuration

If you have this properly configured, adding u...@gmail.com in either order in postfix_vmap should work.
