The short version: Because you're using: X-mailer: Internet Mail Service (5.5.2658.3) The long version: Because they're PGP-signed as per RFC3156, and some vendors don't understand how to deal with multipart/signed mail correctly, and decide that the main text/plain is an attachment rather than a main bodypart (and the last time I tested, even providing an explicit "Content-Disposition: inline" didn't help any). What your MUA *should* be doing if it follows the standards is say "this is a signed mail, but I don't understand the signature format". (And incidentally, the main offenders for this should be *doubly* embarrassed, because they *do* in fact understand multipart/signed, so it isn't even a broken dropback to multipart/mixed - they get stupid when they don't understand the signature type). Complain to your vendor, or use a standards-compliant mail package. I'm told that even Mutt and Pine manage to get it right. -------------- next part -------------- A non-text attachment was scrubbed...
