[Mailman-Users] Very simple content filtering

Hi,

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?

Thanks so much,

John
