Good find - it looks like Mail is using application/pkcs7-signature, while Thunderbird is using , application/x-pkcs7-signature, which is allowed. According to http://en.wikipedia.org/wiki/S/MIME#Caveats, either is an acceptable mime type. So I guess I should email the list admins and ask them to allow that mime type, since they are allowing signatures anyways on the list.Paul Schmehl wrote: > [...]> By default, it appears that Mailman does not do content filtering.

So, it's possible that MIMEDefang is the culprit instead.It's documented in the FreeBSD Handbook: http://freebsd.org/handbook/eresources.html#ERESOURCES-MAILFILTERING Best regards Oliver
