== 4.13. How do I prevent MIME attachments/HTML/Viruses being sent to lists ==
See also the Mailman FAQ entries at [[../How do I turn off HTML messages-attachments?|How do I turn off HTML messages-attachments?]] and [[../Mailman is munging HTML & MIME-formatted messages before they are sent out? (problems with Mailman 2.1.x footers)|Mailman is munging HTML & MIME-formatted messages before they are sent out? (problems with Mailman 2.1.x footers)]].

=== From posting by Alf Christophersen, to mailman-developers on 7 Dec 01 ===
Most of these viruses/attachments come in as MIME encoded, so you can always use [[http://www.phred.org/~alex/stripmime.html|stripmime]], or [[http://scifi.squawk.com/demime.html|demime]] to get that stuff off of the message prior to submitting it to the list. You can go one step further, and look into [[http://www.roaringpenguin.com/mimedefang/|MIMEDefang]], which does a plethora of things for you. There's also [[http://www.johncon.com/john/QuarantineAttachments/|Quarantine]], which will strip out any type of attachments to your message. All of these solutions are external to Mailman (in fact MIMEDefang hooks into sendmail - if you're running it), so you can always end up with "clean" messages going through your list.

An alternative is a MIME handler patch for mailman itself - see
[[http://sourceforge.net/tracker/index.php?func=detail&aid=413752&group_id=103&atid=300103]]
