A long time ago I setup mailman with postfix but not in a jail, from
my notes here is all I had in

/usr/local/mailman/Mailman/mm_cfg.py

IMAGE_LOGOS = '/icons/'
add_virtualhost('lists.foo.com', 'lists.foo.com')
POSTFIX_STYLE_VIRTUAL_DOMAINS = ['lists.foo.com']
DEFAULT_EMAIL_HOST = 'lists.foo.com'
DEFAULT_URL_HOST = 'lists.foo.com'
MTA = 'Postfix'

If you look at /usr/local/etc/mailman/Mailman/Defaults.py and you
haven't changed the directives below in in mm_cfg.py then they are

DELIVERY_MODULE = 'SMTPDirect'
SMTPHOST = 'localhost'

Could it be as simple as postfix is not listening on port 25?

Can you 'telnet localhost 25' and "telnet <your-hosts-ip> 25' 
sucessfully?
