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.

Your copy/paste of the web page is missing some information, namely, which radio buttons are selected.

Should Mailman filter the content of list traffic according to the settings below? [...] No Yes

I assume this is Yes

Remove message attachments that have a matching content type. [...] text/html

Generally, you don't want entries in both filter_mime_types and pass_mime_types, since if you have anything in pass_mime_types, everything else will be filtered whether it's here or not.

Remove message attachments that don't have a matching content type. [...] multipart/alternative message/rfc822 text/plain

So you are accepting only elemental text/plain messages and text/plain parts from multipart/alternative parts. This drops everything that isn't text/plain and also drops text/plain subparts from other multipart types.

For example, if you have a message with structure

multipart/mixed multipart/alternative text/plain text/html application/msword

which is a common structure for a message with an attached ms-word file, you delete everything because you don't accept multipart/mixed.

What you probably want here is something like

multipart message/rfc822 text/plain application/msword application/pdf (etc.)

Remove message attachments that have a matching filename extension. [...] exe bat cmd com pif scr vbs cpl

OK

[...]

Should Mailman collapse multipart/alternative to its first part content? [...] No Yes

This is probably irrelevant in most cases if you don't accept text/html, but unless you want to actuall accept and pass say both text/plain and text/html alternatives, set this to Yes.

Should Mailman convert text/html parts to plain text? This conversion happens after MIME attachments have been stripped. [...] No Yes

This should be Yes, only if you accept text/html, and you set collapse_alternatives to Yes, and you want remaining html parts converted to plain text.
