[Mailman-Users] Weird no-posting no-moderation queue bouncing of posts

2021-02-26 Thread Thomas Gramstad
I have a strange, occasionally occurring phenomenon on one of my 
mailing lists (in Mailman 2.29) which I don't understand:


1. A subscribed address to the list tries to post a message to
   the list.

2. The attempted posting does not go through to the list, nor
   does it go to the moderation queue. Instead, I the list admin
   receives a message via the bounces-address with a copy of the
   attempted posting.

3. The bounce message looks like/similar to the bounce message
   that is generated when a bounce happens at one single
   individual subscriber's e-mail address. But in that case the
   list archive as well as other subscribers (including me)
   will get a copy of the posting. And that is not the case here.
   No copy to me, nothing in the archive.

So the only trace I can see of the posting is the weird bounce 
message containing a copy of the posting.


Why doesn't the attempted posting go to the moderator queue, if 
there is something about the subscriber or the message that 
prevents it from being distributed? (The list in question is 
unmoderated for subscribers.)


Below is a copy of one of the strange bounce postings.

2021-02-26 Thread Bruce Johnson
We get this fairly often with moderated lists; it’s usually because the 
sender’s mail client grabs the listname-bounces address from their recent 
addresses cache when they start typing the address in the mail composition 
dialog.

It would be rarer with unmoderated lists, but anything that would trigger a 
moderation notice (for things like too many recipients, message too large, etc) 
will stick that address in their recent addresses list.

this is the bounce notice we get when that happens:


"The attached message was received as a bounce, but either the bounce
format was not recognized, or no member addresses could be extracted
from it.  This mailing list has been configured to send all
unrecognized bounce messages to the list administrator(s)."

There wasn’t a copy of your bounce on this posting.

It appears, if I read the RFC 5322 mail headers correctly, that the
original mail was sent to LISTNAME-bounces instead of to LISTNAME:

From: =?iso-8859-1?Q?Klev=E5s_Tora_Camilla?= 
To: Biblioteknorge 
Subject: Ledig stilling - Fredrikstad bibliotek - LittFri - et tilb ...

And, of course, this mail is not a bounce message that the bounce
processor can parse.

It is because you have "Should Mailman send you, the list owner, any 
bounce messages that failed to be detected by the bounce processor? 
/Yes/ is recommended." set to yes in your Bounce Processing settings. 
You may need to educate your list members on how to correctly post to 
your list.
