Obviously right. Some people keep sending me email with 3MB attachments, which
annoys me anyway. Since they are impervious to advice, I decided to delete the
attachmenst. I dont't want to remove the whole email though. This worked fine,
until some days ago, when one of them started signing his mail.

This is not an option for me. The signature seems to be an attachment itself,
and I certainly don't want to hack into the MIME structure.

This seems not to work for me (key not bound). What should it do? Strip *all*
attachments? Certainly not what I want.


How can I remove the signature? As said, it's an attachment wihich I failed to
delete due to it's own presence.


Kind regards,
