[Mailman-Users] Relaying issues with Mailman and Postfix

Running Postfix 2.11.7 on FreeBSD 10.2-RELEASE. I am migrating a listserv 
on an older box to this one, running newly-installed Mailman 2.1.20.

I found a one-pager that showed me what to tar up and move over to migrate 
my lists to the new instance of Mailman. Hostname is not changing, so that 
made this part fairly painless.

However I think I'm not even getting that far yet. I'm running into a roadblock 
that I believe is strictly Postfix. So I take it that messages aren't even 
touching the new Mailman daemon yet.

No matter what I do, I am getting relay errors when I send a message with the 
Subject 'help' to <listname>-request at lists.domain.tld, as such:

Oct  3 14:12:20 <servername> postfix/smtpd[67338]: connect from mail.outsidedomain.tld[x.x.x.x]
Oct  3 14:12:20 <servername> postfix/smtpd[67338]: NOQUEUE: reject: RCPT frommail.outsidedomain.tld[x.x.x.x]: 454 4.7.1 <listname-request at lists.domain.tld>: Relay access denied; from=<outsideuser at outsidedomain.tld> to=<listname-request at lists.domain.tld> proto=ESMTP helo=<mail.outsidedomain.tld>

But then additionally I'm noticing these entries as well:

Oct  3 14:09:13 <servername> postfix/qmgr[49782]: warning: connect to transport private/mailman: No such file or directory
Oct  3 14:09:14 <servername> postfix/error[67292]: E587C642A5F: to=<listname-bounces at lists.domain.tld>, relay=none, delay=4801, delays=4801/0.02/0/0.03, dsn=4.3.0, status=deferred (mail transport unavailable)

I tried adding the following, but to no avail:


relay_recipient_maps = hash:/usr/local/etc/postfix/relay_recipients

transport_maps = hash:/usr/local/etc/postfix/transport


(for each list)
listname at lists.domain.tld OK
listname-listname at lists.domain.tld OK
listname-bounces at lists.domain.tld OK
listname-confirm at lists.domain.tld OK
listname-join at lists.domain.tld OK
listname-leave at lists.domain.tld OK
listname-owner at lists.domain.tld OK
listname-request at lists.domain.tld OK
listname-subscribe at lists.domain.tld OK
listname-unsubscribe at lists.domain.tld OK


lists.domain.tld mailman:

I then postmap'ed relay_recipients and transport and restarted postfix. Even 
restarted mailman for good measure. But no such luck.

My only suspicion is that maybe in Postfix 2.11.7, I need to do something in 
MySQL/PostfixAdmin concerning this line in main.cf?:

relay_domains = proxy:mysql:/usr/local/etc/postfix/mysql_relay_domains_maps.cf

Any assistance or advice, as always, would be greatly appreciated!
