[Mailman-Users] cause of bounces

Tue Oct 10 02:56:02 EDT 2017

Hi and hope the answer(s) to my question are relatively simple. On one of two lists I manage, some people are getting deleted due to too many bounces.  And the bounces seem to be related to their mail provider not allowing the messages.   As far as I can tell, the main culprits are gmail, yahoo, and hotmail.

Of course, those people blame Mailman.  From what i have read, it is not necessarily that. But complicating things is that people were complaining that the default REPLY to SENDER was not appropriate for a discussion list, so I just switched it over to REPLY TO GROUP. I do not THINK that is the reason for the trouble, but here in the space of a few minutes are some of the messages I have gotten with my questions in caps.

PROBLEM ONE

UNABLE TO SEND? RECEIVE?

a at yahoo.com <mailto:a at yahoo.com> 
host mta7.am0.yahoodns.net <http://mta7.am0.yahoodns.net/> [66.196.118.37]
   SMTP error from remote mail server after end of data:
   554 5.7.9 Message not accepted for policy reasons.  See https://help.yahoo.com/kb/postmaster/SLN7253.html <https://help.yahoo.com/kb/postmaster/SLN7253.html>

SEEMS TO BE YAHOO DOE SNOT LIKE MAILMAN AND ALSO SHE CANNOT ADD MAILMAN TO A WHITE LIST (THEY DO NOT HAVE).—>

IS IT POSSIBLE SHE IS USING A MAIL CLENT THAT DOES NOT SEND CORRECTLY? OR IS THIS THE YAHOO INTERACE?

IS THIS HER MESSAGE BEING SENT OR HER MAIL PROGRAM NOT ACCEPTING MESSAGES?

RELATED TO THIS:

Some people are getting unsubscribed as a result:

   List:       Galeexec
   Member      ie at hotmail.com <mailto:mccandie at hotmail.com>
   Action:     Subscription disabled.
   Reason:     Excessive or fatal bounces.

CAUSE OF ALL THE ABOVE?
SOLUTIONS—BY LIST OWNER?   BY MEMBER?

NEXT
hn at hotmail.com <mailto:hn at hotmail.com>
  host hotmail-com.olc.protection.outlook.com <http://hotmail-com.olc.protection.outlook.com/> [104.44.194.233]
   SMTP error from remote mail server after end of data:
   550 5.7.0 (SNT004-MC7F11) Unfortunately, messages from (199.223.209.221) on behalf of (yahoo.com <http://yahoo.com/>) could not be delivered due to domain owner policy restrictions.

SAME THING?  I note the user has a hotmail address.

BELOW THAT IS MORE INFO (RELATED TO THE ABOVE?)

RESPECTIVELY 

Action: failed
Final-Recipient: rfc822;ya at yahoo.com <mailto:quenbya at yahoo.com>
Status: 5.0.0
Remote-MTA: dns; mta7.am0.yahoodns.net <http://mta7.am0.yahoodns.net/>

Action: failed
Final-Recipient: rfc822; hn at hotmail.com <mailto:hn at hotmail.com>
Status: 5.0.0
Remote-MTA: dns; hotmail-com.olc.protection.outlook.com <http://hotmail-com.olc.protection.outlook.com/>

There are others like this and they all share one of the two providers. 

PROBLEM TWO
Though GMAIL USERS have reported messages in SPAM. No errors messages to the list.
