I want to allow only certain types of files for the lists. Ok, I'm using pass_mime_types including lines like these:

text/plain application/pdf application/msword application/vnd.ms-excel

I was testing and I noted that it works different according to the email client. For example, an excel file sent from an old Netscape is stripped out by Mailman, but from Open Webmail or from Pine it passes!

Is there some solution on the server/Mailman side in order to allow certain files based on its extension no matter the mime type?

Thanks,

Pablo Chamorro C.
