Hi Mark,
Thank you for your reply.
I admit that I don't know Mailman 3 as well as I knew Mailman 2. And the 2 -> 3
upgrade was handled by someone else, who has since left the org. As near as I
have been able to discern, Mailman 3 is running on a docker host with four
containers running, with mailman, postfix, nginx and django-uswgi in separate
containers.
% sudo docker ps

mailman-core
When I look at main.cf inside mailman-postfix:
transport_maps =
hash:/opt/mailman/var/data/postfix_lmtp
local_recipient_maps =
hash:/opt/mailman/var/data/postfix_lmtp
relay_domains =
hash:/opt/mailman/var/data/postfix_domains
virtual_alias_maps =
hash:/opt/mailman/var/data/postfix_vmap-exceptions,
hash:/opt/mailman/var/data/postfix_vmap
When I look at the domains in mailman-core, I see:
>>> show_domains()
<Domain fhcrc.org>
<Domain fredhutch.org>
<Domain lists.fhcrc.org, , alias: lists.fredhutch.org>
<Domain lists.hanc.info, , alias: >
- owner: cit-sys-engineer...@fredhutch.org
>>>
When I look at /opt/mailman/var/data/postfix_domains inside the postfix
container, that seems to match:
fredhutch.org fredhutch.org
lists.fredhutch.org lists.fhcrc.org
lists.hanc.info lists.hanc.info
Now, when I look at the entries for a test list on lists.fhcrc.org,
postfix_vmap looks like:
patt...@lists.fhcrc.org patt...@lists.fredhutch.org
pattest-boun...@lists.fhcrc.org
pattest-boun...@lists.fredhutch.org
pattest-conf...@lists.fhcrc.org
pattest-conf...@lists.fredhutch.org
pattest-j...@lists.fhcrc.org
pattest-j...@lists.fredhutch.org
pattest-le...@lists.fhcrc.org
pattest-le...@lists.fredhutch.org
pattest-ow...@lists.fhcrc.org
pattest-ow...@lists.fredhutch.org
pattest-requ...@lists.fhcrc.org
pattest-requ...@lists.fredhutch.org
pattest-subscr...@lists.fhcrc.org
pattest-subscr...@lists.fredhutch.org
pattest-unsubscr...@lists.fhcrc.org
pattest-unsubscr...@lists.fredhutch.org
and postfix_lmtp looks like:
patt...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-boun...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-conf...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-j...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-le...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-ow...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-requ...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-subscr...@lists.fredhutch.org lmtp:[mailman-core]:24
pattest-unsubscr...@lists.fredhutch.org lmtp:[mailman-core]:24
But for a test list on lists.hanc.info (the lists that I want to modify the
bounce processing for), there is nothing in postfix_vmap, but there are entries
in postfix_lmtp:
pht...@lists.hanc.info lmtp:[mailman-core]:24
phtest-boun...@lists.hanc.info lmtp:[mailman-core]:24
phtest-conf...@lists.hanc.info lmtp:[mailman-core]:24
phtest-j...@lists.hanc.info lmtp:[mailman-core]:24
phtest-le...@lists.hanc.info lmtp:[mailman-core]:24
phtest-ow...@lists.hanc.info lmtp:[mailman-core]:24
phtest-requ...@lists.hanc.info lmtp:[mailman-core]:24
phtest-subscr...@lists.hanc.info lmtp:[mailman-core]:24
phtest-unsubscr...@lists.hanc.info lmtp:[mailman-core]:24
And in postfix_vmap-exceptions, I added:
phtest-boun...@lists.hanc.info lmtp:[mailman-core]:24,
u...@gmail.com
I tried the above with and without a comma, and moving the email address before
the lmtp entry as well.
Everything else seems to be working — there are over 40k lmtp: entries in
postfix_lmtp, and messages are being delivered. I sort of assumed that the
lmtp:[mailman-core]:24 thing was a result of all this being dockerized....
Suggestions appreciated.
Thanks,

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.

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://urldefense.com/v3/__https://docs.mailman3.org/projects/mailman/en/latest/src/mailman/docs/mta.html*unusual-postfix-configuration__;Iw!!GuAItXPztq0!lk52z6S25pPCaLuRNT4aZ5V0dcMaO1c2hkv7JZB93ZVBRtNlyZ6plEr4m485PGc5Iga1dOjnX948WP8$
If you have this properly configured, adding u...@gmail.com in either
order in postfix_vmap should work.
