[Mailman-Users] e-mails being kind of blackholed when sent to list or list-robot

Folks,
I'm running a Ubuntu with Postfix and Mailman. Everything was up and
running, and somehow mailman started to fail (we migrated the virtual
machine to a different container, but I'd expect this to be orthogonal..
so.. not sure what happened).
Essentially, any emails that I send to the mail-robot aliases (e.g.
listname-request at mydomain.com) are kind of blackholed: I don't get a
response from mailman, but I also don't get any sort of "user unknown
message" either.
Similarly, if I try to post to the list, the messages vanish (they are
not forwarded to the subscribers but you don't get a "reject", either).
Bellow you'll find my Postfix cnfig and my mm_cfg.py, plus some notes on
some debugging I tried to do.
This is my Postfix config (postconf -n):

If I look at /var/log/mail.info, I can see that my messages (the one I
set to the robot ipv6hackers-request at lists.si6networks.com, and the one
where I tried to post to the list at ipv6hackers at lists.si6netwoks.com)
have been handled to mailman, aparently:

But the logs in var/log/mailman remain unaffected.
By the way, I did run check_perms and everything seems fine.
Any help will be really appreciated.
Thanks!
Cheers,
