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...@yahoo.com <mailto:a...@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      i...@hotmail.com <mailto:mccan...@hotmail.com>
   Action:     Subscription disabled.
   Reason:     Excessive or fatal bounces.


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


NEXT
h...@hotmail.com <mailto:h...@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.  

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


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

RESPECTIVELY 


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

https://help.yahoo.com/kb/postmaster/SLN7253.html 
<https://help.yahoo.com/kb/postmaster/SLN7253.html>

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

(199.223.209.221) on behalf of (yahoo.com <http://yahoo.com/>) could not be 
delivered due to domain owner policy restrictions.

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.

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

Thank you very much.
