I have set up mailman.
I have set up a virtual domain for mailman in the mm_cfg.py via the
add_virtualhost() function.
I have successfully created the list. I subscribed to the list, got the
confirmation note and confirmed. when I went to send a message to the
mailing list, I get a user unknown.
In the mm_cfg.py
MTA = none
DEFAULT_EMAIL_HOST = 'lists.xyonet.com'
DEFAULT_URL_HOST = 'lists.xyonet.com'
add_virtualhost(DEFAULT_URL_HOST, DEFAULT_EMAIL_HOST)
add_virtualhost('lists.delrc.org', 'lists.delrc.org')
I get my transports from a database and that is working since I'm
getting other mail via the local delivery agent.
the transport entry is:
lists.xyonet.com mailman
lists.delrc.org mailman
Then in the master.cf i have
mailman unix - n n - - pipe flags=FR
user=list argv=/etc/mailman/postfix-to-mailman.py ${nexthop} ${mailbox}
main.cf
transport_map =
