Public bug reported: When attempting to send a signed S/MIME message with evolution, the mail is sent as multipart/mixed instead of multipart/signed, thereby preventing signature validation. GPG signed messages are formatted and verified correctly. S/MIME signatures from other mailers are also verified correctly by Evolution itself.
Expected header: Content-Type: multipart/signed; protocol="application/x-pkcs7-signature"; micalg="SHA1"; boundary="----=_NextPart_000_0097_01CC529D.8F3107C0" Actual header: Content-Type: multipart/mixed; boundary="=-y1IUcclJdzFtE471smGQ" Ubuntu Release: 11.04 evolution: Installed: 2.32.2-0ubuntu7 Candidate: 2.32.2-0ubuntu7 Version table: *** 2.32.2-0ubuntu7 0 500 http://de.archive.ubuntu.com/ubuntu/ natty/main amd64 Packages 100 /var/lib/dpkg/status ** Affects: evolution (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/820899 Title: S/MIME signature broken due to wrong MIME multipart header To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/evolution/+bug/820899/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
