Hi, I don't that I need to remark that bypassing is MIME is a Bad Thing. For the concrete problem some people have with OpenPGP signatures (i.e. seeing an unknown attachment and fearing malware) a simple and well working solution: Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part. or better with a more descriptive file name as Outlook does it: Content-Type: application/pgp-signature; name="openpgp-digital-signature.asc" This tell the user what the attachment is about and 95% of all questions are solved. Sure, this does not help against stupid enterprise style mail filters which tend break mails for fun and no-profit. Not just attachments, but are also reordering parts and some even modifying header lines. Shalom-Salam, Werner -- The pioneers of a warless world are the youth that refuse military service. - A.
