The name "permit_auth_destination" means that when the domain part of
the recipient is *authorized*, Postfix should proceed to route the
mail to final delivery. It can still be rejected (for example, if the
"user" part doesn't exist at "domain"), but checking that the final
destination host is authorized is an easy and cheap first screen.
The two bullet points *define* "authorized". Both contain the phrase
"and the address contains no sender-specified routing". This
condition is imposed because
(1) you can't be sure that the MTA at "domain" will relay to
"elsewhere" rather than "spyagency, so stripping off
"user@elsewhere" and checking if "elsewhere" is authorized isn't
reliable, and
(2) on the modern Internet there's no need for sender-specified
routing anyway.
Both bullet points start with "Postfix is ...", but more fully this
should be "Postfix is acting to ... this message".
The first bullet point then is saying "when the domain matches
$relay_domains or a subdomain, go ahead and relay." In other words,
this Postfix is acting as the MX for the domains in $relay_domains.
The second bullet point is more complex, but it basically amounts to
various ways of saying "the final destination is local", or more
formally, under administrative control of the Postfix administrator
(and that's the difference with relay_domains, which are cooperative
agreements with those domains, but not controlled by this Postfix's
administrator). To understand why each of those variables means
"local", I'll ask you to look first at the Postfix docs because I'm
getting tired ;-): https://www.postfix.org/postconf.5.html.

That sounds right to me based on our conversations, but if you change
your mind and decide you want to add more conditions, feel free to
consult then.

Yes, I think it's best to require that access to 'su mailman' be
restricted to root and/or sudo.

Good luck!

I don't understand why this would not be delivered. My best guess
would be that you have "sugarlabs.org" in $mydomain (this is actually
Postfix's default), so that Postfix thinks lists.sugarlabs.org is a
mail gateway for the parent domain. What "mail gateway" means is that
this host has direct write access to mailboxes "at" that domain. This
could be because it's a local or network file system mounted on this
host, or it could be a network transport to an IMAP server, that kind
of thing. But "lists" isn't a gateway in that sense.

Yes, I think that what's happening is that "something went wrong" and
some error message was mailed back to <mailman(a)lists.sugarlabs.org>.

I'll have to look at why the confirmation email gets bounced later, this is

I've changed mydomain to lists.sugarlabs.org, and tried again, let's see if

Mark,
Ok I have it almost perfectly working now having taken your direction and configuring a unique domain not in my email system already.
But in my testing, I replied to a subscription confirmation message and received back an undeliverable looping email error message from postfix. Any clues there you can offer? I can post to the list from any email added via the admin console. The test subscriber address was local to my server. From an outside address, same error.
Once I registered the new email domain, I reverted my postfix config back to the default suggested by maxking's docker instructions.

Thanks.

I have issue where it does not send emails on to people in the list I create.
by john_warland＠hotmail.com
Hello,
I am quite new to Mailman3 and have been trying to get a working local test setup on a single VM (Centos07)
I have issue where if I send an email to the list. it does not send emails on to the people subscribed to that list.
Note the steps below were put together from memory after a few days of repeatably trying different things so there will be some inaccuracies
I have mailman running on same local box as postfix, postorius and hyperkitty.
I have root as the superuser in Postorius and have tried the following:
In unix shell created new user 'developer'
In unix shell created new user 'tester'
In shell send an email from developer user to tester:
echo 'Hello' | mailx -s 'Hello Subject line' tester(a)sandbox.mytest.com
Confirmed user tester received email in cat /home/tester/Maildir/new/ folder:
Return-Path: <developer(a)cloud7.sandbox.mytest.com>
X-Original-To: tester(a)cloud7.sandbox.mytest.com
Delivered-To: tester(a)cloud7.sandbox.mytest.com
Received: by cloud7.sandbox.mytest.com (Postfix, from userid 1000)
In Postorius web frontend:
Signed up as root
Received confirmation email in /root/Maildir/new/ folder so cut and pasted the Url in the email to activate account.
Created new list called testlist(a)sandbox.mytest.com
Logged out
Signed up as tester
Received confirmation email in /home/tester/Maildir/new/ folder so cut and pasted the Url to activate account.
Subscribed tester to the testlist.
Next in unix shell su as developer and send an email to testlist(a)sandbox.mytest.com
The root user gets the following email
Content-Transfer-Encoding: 7bit
Subject: Your message to testlist(a)cloud7.sandbox.mytest.com awaits moderator approval

Your mail to 'testlist(a)cloud7.sandbox.mytest.com' with the subject
hello there 2
Is being held until the list moderator can review it for approval.
The message is being held because:
The message is not from a list member
Either the message will get posted to the list, or you will receive notification of the moderator's decision.
Once I have gone back into Postorius as root and approved the message, root user gets a second email:

First, thanks for your patience. Two steps forward and one step back,
here. I have the interface running and I can create a list which
*does* send messages to my test recipients.
To answer your question, yes, I did all that, and that generates
postfix_domains and postfix_lmtp, but not postfix_vmap. Here's what I
got:
$more postfix_domains
# AUTOMATICALLY GENERATED BY MAILMAN ON 2021-12-26 22:29:27
#
# This file is generated by Mailman, and is kept in sync with the

# you're on your own.
libertyfp.org libertyfp.org
$more postfix_lmtp
# AUTOMATICALLY GENERATED BY MAILMAN ON 2021-12-26 22:29:27
#
# This file is generated by Mailman, and is kept in sync with the

# Aliases which are visible only in the @libertyfp.org domain.
testlist(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024
testlist-bounces(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024
testlist-confirm(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024
testlist-join(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024

testlist-subscribe(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024
testlist-unsubscribe(a)libertyfp.org lmtp:[mail.libertyfp.org]:8024
But no postfix_vmap.
However, let me ask another question first:
When running mailman3, do I need to set up a completely different
virtual domain for it to run in? My "real" domain name is
libertyfp.org, and I'm trying to make mailman work on that domain, e.g.
"testlist(a)libertyfp.org." I'm starting to get the idea that I need to
stick a completely different domain in there for the mailinglist.
Which I can do -- I've got another two or three domain names to play
with. Is it a problem to run the mailinglist on the same domain that
the machine sits on for its regular business? A lot of the errors I'm
getting seem to be from trying to do regular mail *and* the mailinglist
on the same domain.
Now that I've installed all this stuff a couple of times, I can easily
re-install for a second virtual domain, if that's what I should be
doing.
But, on to what's not working now...
Unfortunately, I seem to have completely screwed the pooch on getting
postfix/dovecot to play nicely with respect to *receiving* mail.
First, adding "virtual_alias_domains" (and putting libertyfp.org in it)
and commenting out "virtual_mailbox_domains" resulted in postfix
ignoring all my virtual mailboxes. Mail still worked, but mail is now
being sent to /home/<user>/Maildir instead of
/home/vmail/libertyfp/<user>/Maildir -- which means that dovecot, which
looks in the virtual mailboxes, is now unaware of new mail. I suppose
I could link /home/<user>/Maildir to
/home/vmail/libertyfp.org/<user>/Maildir, but I suspect there will be
problems and it's not a real fix. But.. .a problem for another day.
Except... the same thing is happening with the mailinglist.
In mailman3:
I set up a test list (testlist(a)libertyfp.org) and added two test users
(one local and one on a different domain). They added just fine, and
both received the welcome message.
However, when I replied, both messages bounced with the error that
"testlist(a)libertyfp.org" was "user unknown in virtual alias table."
No problem, I thought. So I added:
testlist(a)libertyfp.org testlist
to /etc/postfix/virtual, and
testlist libertyfp.org/testlist/Maildir
to /etc/postfix/virtual-mailbox,
and I added testlist as a user:
$ adduser -m testlist
So, now mail from my list members goes to /home/testlist/Maildir, but
not to the mailinglist.
I also have managed to get another *different* warning, and the "there
ain't no vmap, newbie" error as well:

That "you can't have both virtual_alias_domains" and "relay_domains"
seems like it should be a clue. But I don't' know what for. Adding
virtual_alias_domains really changed things...
Anyway, here's the part of the /etc/postfix/main.cf that I think is
likely important. Note that I comments out "virtual_mailbox_domains".

Re: Issues with Mail delivery after Mailman 3 installation
by Chihurumnaya Ibiam
After making the above changes I talked about, mail transfer seems to work
as expected,
although I noticed users signing up don't get their confirmation emails
delivered for some reason, saw this in the logs;
(1632818) <177024281405.1632816.13618430493699791595(a)localhost.localdomain>
delivery to ibiam(a)sugarlabs.org failed with code 550, b'5.1.1 <
ibiam(a)sugarlabs.org>: Recipient address rejected: User unknown in local
recipient table'
What would be the best way to ensure that these get delivered?
Thank you for all your help, I really appreciate it.
I think I went into this rabbit hole because of this particular issue
above, and I thought something was wrong, mail was always sent to the
mailman user
and I thought that was odd, but now I know that's expected as that's the
user that Mailman runs on.
