[Mailman-Users] Strange problem with mails through mailman

[Kim Leandersson]

Hello!

I have a strange problem that I think depends on mailman. We have a bunch of mailman lists here for different assosciations and some of the administrators complains that all the members don't get the mails. When I looked into it I found some strange errors in the logs. The mails for the people that don't get the list mails are all deferred from the receiving mail server because of bad media type or Body type not supported by Remote Host (see end of the mail for more details). I can't see why this error should occur, and why it only occurs on certain servers. Another thing that I can't understand is that it's only mail via mailman that bounces. If I send a mail directly to these people there are no problem att all, and one of the people that don't get list mails are a list administrator. She don't get the mails she sends out, but she gets administrative messages from mailman.

Anyone who can point me in some direction so I can solve these problems? Does mailman change the body type in some way? 


Bounce message from mailman when I tried to send a mail to the list.
