Getting a "mail forwarding loop" notice for messages sent to discuss
list. Does that mean anything to anybody?

Tyler,

Markus has observed the same thing, and filed a ticket about it -
hmm, I can't find it. Perhaps he did not.

I've looked into it briefly and I have no idea what is going wrong.
I'm hoping someone more email savvy than me will look into it.

Best regards,

This is most likely caused by a tiny Postfix configuration issue wrt.
those domains/hosts which are to be considered as being local ones.
I'll try to dig into it later today (didn't have many spare cycles
during the past days),

I did not because trac was down when it happened. So I reported
in this list.

Something must have been changed a week or so ago.

.... at least not on the Postfix side: All the config files have been
unchanged since 2008.
The error message doesn't look unfamiliar to me and/but in most of the
cases the 'common' recipes didn't work. I'll have to have a closer look
at the error message, maybe we're having a situation where a Postfix
configuration fault is being triggered after a recent change in one of
the lists ?

BTW, for the server migration I propose to add a mailman transport for
Postfix - yes, and I'm willing to add the respective configuration :slight_smile:

Cheers,
  Martin.

I suspect that user "arnaud.degroof@spacebel.be" has set up an OSgeo

Cool - does mailman end up unsubscribing these kinds of loops?

Even if it could, the looped EMail doesn't get that far down in the
queue. Instead, Postfix detects the loop via the "Delivered-To" header
before the looped EMail gets handed over to Mailman.

BTW, while doing diagnostics, I had accidentially disabled the Mailman
list addresses for a while, so a couple of people might have gotten
"Recipient unknown" messages when sending EMail to a list (due to the
fact that 'postmap' doesn't handle the Mailman aliases table format).

Things are now back in proper state - otherwise you would not have been
able to read my previous message. I'm very sorry,

  Martin.

Martin,

I have marked this subscriber to the discuss list as "nomail".

Folks - if the problem persists let me know.

Will this help avoid the problem Markus and Tyler experienced?

I should probably add a little comment:

The messages people have seen here (related to the loop) do _not_
indicate a mailing list malfunction. Every list submission has been
delivered properly to the list and to every of it's recipients (at
least those who have a functional inbox).

The respective list-maintainers are encouraged to deal with the
situation either by removing the mentioned address from their lists -
and probably tell the candidate why they're doing so - or, maybe
preferred, at least by asking him to check his EMail settings. As far
as I can tell, the user in question is subscribed to the following
lists:

  Discuss, Francophone, mapguide-users

Cheers,
  Martin.

I can follow up with the user, unless someone else has tried to.

No, it won't. Adding a mailman transport is just providing a short-cut
between Postfix and Mailman, thus circumventing the aliases lookup of
the local delivery for incoming list submissions.
