Okay, that’s good. I did exactly the same ;)

It’s not quite clear to me if your problem is getting Postfix to deliver to mailman, or mailman to postfix.

In my setup the list is on a separate (virtual) domain, and uses an aliases file 
(alias_maps = hash:/etc/aliases, hash:/usr/local/mailman/data/aliases).
That file is maintained by mailman and will have things like 'test:             "|/usr/local/mailman/mail/mailman post test”’ in it.

Return delivery (i.e. mailman sending mail) is done using the DirectSMTP module. My ‘SMTPHOST’ is set to the hostname of the jail (so to an IP address the postfix is listening on). If you’ve still got that set to the default of ‘localhost’ that might also explain your problems.
It might also be worth playing with telnet inside the jail and confirming that you can talk to your postfix that way.
