[Mailman-Users] Handling Attachments and More

[David Andrews]

I have a Sun Cobalt RAQ550 with Mailman 2.1.8 installed, and running 
about 120 lists.  We were having problems with the setup handling 
multi-part messages that contained text and html -- some mail 
programs reproduced stuff twice etc.  Also we need to pass attachments.

On the advice of someone I made some changes, content filtering 
settings below, and while the multi-part thing is a little better, it 
only passes text attachments.  Need to pass .doc etc.

I am obviously not an expert in this stuff, or I wouldn't be 
bothering all of you.  Any suggestions would be appreciated.

Should Mailman filter the content of list traffic according to the 
settings below?
