We are using Mailman 2.1.9. I'd like to be able to strip potentially dangerous attachments, exe, bat, scr and the like, while leaving virtually everything else about the message intact so that readers see the messages as the composers intended them, often in html with inline graphics and so forth. No combination of settings I have tried seems to accomplish this. What content filtering settings would you recommend?

If you want to filter only based on attachment file name extension, set

filter_content = Yes

filter_mime_types Empty

pass_mime_types Empty

filter_filename_extensions exe bat cmd com pif scr vbs cpl

(or what ever list you want)

pass_filename_extensions Empty

collapse_alternatives = No

convert_html_to_plaintext = No

filter_action As desired for messages that consist entirely of parts with file names with the unwanted extension (it is not likely there will be such messages and almost all messages have a text body with no filename).
