There was a recent security advisory involving sendmail and MIME attachments that could be related to this. I don't understand what business sendmail has even *looking* at the MIME structure of a message, let alone mucking about with it. I'd say use that as yet another reason to change to a different MTA. (I noticed that NetBSD seems to have removed sendmail from the base system altogether in recent current, in favour of postfix...) Cheers, -- Andrew
