[Mailman-Users] Rejecting emails with certain types of attachments

[Titus von der Malsburg]

Hi list,

is it possible to automatically reject emails that have attachments with
certain MIME types (e.g., application/msword, …)?

Since there are so many types of files that are unsafe, I also wonder
whether it is possible to specify a white list of safe MIME types (e.g.,
application/PDF) and to reject everything else.  Is that possible?

I did some searching but only found solutions for automatically
stripping attachments, which is not what I want.

Thank you,

  Titus
