This tells you that localhost.localdomain is listening on the smtp port
(port 25) for connects from anyone.

This should be OK, but the fact remains that when you actually connect
with either Mailman or telnet you get no response from Postfix (if
that's what's listening).

This is almost certainly a Postfix configuration issue. If you are able
to send mail from this box at all, what is the MUA connecting to?

What happens if you try

telnet localhost.localdomain 25

is that any different from

telnet localhost 25

(It shouldn't be, but who knows.) If it turns out that Postfix is
listening on some other address/port, you can set SMTPHOST and
SMTPPORT in mm_cfg.py to make Mailman use the ones that work.
