Package: mailman Version: 2.1.5-8 Yo!
The MIME parser mailman seems to do some header sanitizing, at least for
message/rfc822 attachments. This is problematic as it breaks the PGP
signature on the mail:
My case: mail was
multipart/signed [ text/plain message/rfc822 [
multipart/signed [ text/plain application/pgp-signature ]
] ]
when it was fed to mailman. mailman of course wrapps that in
multipart/mixed to add the unsubscribe instructions, and additionally
breaks long header lines of the inner message/rfc822 (IIRC the outer
headers where similarly sanitized, but as they're not signed it doesn't
matter.)
mailman has been identified as the culprit imho - I've sent a mail with the
same structure over the same server, but directly to an account instead of
mailman, and the signature arrived intact.
