Here the message was properly posted to the mail wrapper which queued
it. Everything up to this point is good.

Your localhost is connecting via IPv6.

Here Mailman is trying to send the post to the list members or maybe
sending a notice to the list moderators and Postfix won't relay to those
addresses.

I assume this is really mm_cfg.py, but I don't think any of it is
relevant to this issue.

And this I assume in main.cf. Tip: in general people don't want to see
your main.cf. It's too unwieldy. You should post the output from
'postconf -n'.

mydestination doesn't include the uerj.br domain.

and mynetworks does not include the IPv6 address of localhost. Thus,
uerj.br is not a local domain and the originating server is not in what
Postfix is told is the local network so Postfix won't relay the mail.

There are various ways to fix this.

1) add either localhost or ::1 to mynetworks.

2) edit /etc/hosts so that the name localhost is 127.0.0.1 instead of ::1

3) put

SMTPHOST = 'the /etc/hosts name of 127.0.0.1'

in mm_cfg.py.

These three solutions are mutually exclusive. You only need one of them.
Which one is best depends on what else your server is used for.
