I would like to have all outgoing mails signed with pgp/gpg. Has anybody already done this? I think this could probably best be implemented by creating a Kernel::System::Email::GPG module or something like that?
We're currently thinking about implementing this, yes.

All right, I have taken the discussion into the [dev] mailing list. In the meantime, I have done a quick and primitive hack starting from the Kernel::System::Email::Sendmail module. It is a very unsophisticated module that clearsigns all outgoing messages using one single PGP key. I have put it on the web at http://www.net-track.ch/misc/support/otrs/ I haven't done extensive testing - on the contrary, it's really just a quick hack in order to test if and how it is possible and what problems arise. Has anybody else done some work on this problem? Regards Oliver

After having observed that this is definitely NOT the way to go, I have now tried to implement pgp signing inside the module Kernel::System::Ticket::SendArticle. By the way, you guys wrote very readable code! Thanks a lot! The new approach is much cleaner. It no longer clear-signs the message, but transforms it to multipart/signed and adds an attachment containing the signature to it. This way, the attachments are signed as well and they are not messed up. I don't know if all MUAs support multipart/signed. It works with mutt, but chances are that other MUAs will show your message in an attachment. I'd be glad if others could try the patch and report back any problems. You can download the patch at:
