Which tells you to use the third party postfix-to-mailman.py module for
mail delivery to Mailman, and which appears to be defective[1].
When I created the list the administrator received the e-mail the
list was created.
Then subscribed to the new list with a different e-mail and again
received the confirmation e-mail.
So outgoing mail from Mailman works. This of course does not involve
postfix-to-mailman.py.
Then I sent an e-mail to test at lists.example.com
as the administrator and nothing
happens. No bounce back, no e-mail sent, nothing archived it's like
it just go out to no man?s land.
I have to admit I suck and Linux so please try to keep it simple.
Looks in your Postfix log (/var/log/maillog, or wherever it is) and find
out what Postfix did with the message. If it successfully delivered it
via the 'mailman' relay/transport, it should have been queued in
Mailman's in/ queue (/var/spool/mailman/in in CentOS/RHEL). If not, the
Postfix log should give you a clue. Note, it must have been delivered
via the 'mailman' relay/transport. Any other delivery, e.g. to a
mailbox, won't work and indicates that Postfix' transport table doesn't
contain the
If it got successfully queued, see the FAQ at

potentially relevant to your situation).
[1] Your referenced howto appears to omit a crucial piece. You must add
lists.example.com mailman:
to /etc/postfix/transport and then run 'postmap /etc/postfix/transport'.
Also, the postfix-to-mailman.py it tells you to use is broken for
current RHEL/CentOS because it assumes you can set a single MailmanHome
directory which contains both the lists/ directory and the mail/mailman
wrapper, but in current RHEL/CentOS these are /var/lib/mailman/lists and
/usr/lib/mailman/mail/mailman respectively.
Finally, it does mention
* Let do piping on postfix in order to deliver mailman lists.
mailman unix - n n - - pipe
flags=FR user=mailman:mailman
argv=/usr/lib/mailman/bin/postfix-to-mailman.py ${nexthop} ${mailbox}
but it doesn't say where (master.cf) to put that.
