Arrgggg! You are correct. In all my machinations I forgot to uncomment that line. However, I'm getting something I don't understand which may be a mailman related issue. When mail is received from [email protected] it appears to be going back to gmail rather than being intercepted and processed by mailman.

I realize there are separate processes there but that is what comes out every time mail is received from gmail. I'm not sure what causes mail to be intercepted by mailman but it must be a configuration issue. These are all generated automatically by the mailman install.

main.cf:

transport_maps = hash:/opt/mailman/mm/var/data/postfix_lmtp
local_recipient_maps = hash:/opt/mailman/mm/var/data/postfix_lmtp
relay_domains = hash:/opt/mailman/mm/var/data/postfix_domains

postfix_lmtp:
