Thanks. I wrote "mime-cipher" and "mime-sign-message-digest" but I actually had it correctly with an "s" in front.

I verified that the problem remains even with cipher DES3 and digest MD5. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1640190 Title: S/MIME encryption broken To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/s-nail/+bug/1640190/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
