        Hello all / @aheinecke,

        recent changes seem to have solved above problems for encryption - gpg-signatures still are broken:

        Gpg4win + Outlook + Kopano OL + Z-Push + Kopano-core + Kopano-webapp produces valid output for GpgOL generated mails.

        Tested 2018-06-19 15:17 CEST with :

        core kc-git-master 8.6.80.1128
        webapp git-master 3.4.15final.221-ga3347f1
        z-push 2.4.3.beta1+6
        GpgOL 2.06
        KOE 3.0.305
        Outlook 16.0.4639

        WebApp received representation of a mail composed in Outlook with GpgOL as below:

          Malheureusement, the above said is valid for gpg-encryption, only.
          If the mail ist gpg-signed, too or only, the mail arrives with an attachment unknown_content_type.bin containing either the pgp-signature, or the string Version: 1. Additionally, the decrypted body contains MIME-tags.

              …and now the good better news:

              gpg-encryption & signature works as expected for PGP/Inline-messages with GpgOL v2.2.0, which is part of recent Gpg4win 3.1.2 .

              It still fails with wrongly constructed/ parsed MIME-multipart elements (unknown_content_type.bin), unencrypted attachments etc. as soon as Content-Type: multipart/mixed MIME-structures are involved.

                  Hi,

                  how is the actual state of this point? Is it solved?

                  I’m wondering if this problem maybe could be a problem of gpb4win and not kopano: there is a alternative gpg plugin existing for outlook 2016 (and other versions) called gpg4o that works perfectly with outlook and kopano.

                  If you need further data, please let me know…

                  Kind regards

                  Rolf

                      @fbartels thats unfortunately just 50%.

                      • It still doesnt work when sending crypted (and optionally signed) messages with attachments.
                      • with attachments it just works when receive
                      • the way to use pgp/inline is just a workaround and NOT a solution.

                      sorry, but the bug is still existing and prevents the usage of a lot of pgp usecases.

                      is there the possibility that this may be solved this year? That’ll be great :-)

                      Kind regards

                        PGP currently isn’t a priority for us at Kopano. If an external developer want to dive into this then patches are welcome.

                          Hello,
                          I just want to ask if there are any news on this topic. I have a client who licensed a new Kopano subscription (30 Users). My client has the same problems as described above. The use of GPG/PGP encryption is a must have in this case.

                          I hope we can find a solution on this topic?

                              @fbartels Thank you for your quick reply. That are very sad news for me.

                              I have done some tests this morning and I can confirm, that the KOE is not affecting this problem. I created a new ActiveSync account on Outlook 2016 without KOE installed. The problems are exact the same as described above:

                              • Sending encrypted/signed mails does not work.
                              • Sending encrypted/signed mails with attachments does not work.
                              • Fallback to PGP/Inline works without attachments.
                              • Receiving all kind of E-Mails with Outlook/GpgOL works. So only outgoing mails are affected.

                              All my tests where on Outlook 2016/GpgOL-Extension connected via ActiveSync to Kopano. The test-receiver was an external IMAP-Account with Thunderbird/Enigmail.

                              My client has a subscription. So I will contact the support on Tuesday. I hope there will be a solution with a higher priority than before.

                              Regards, Robert.

                                Hi,
                                I forgot about this thread but it was recently mentioned again in our tracker.
                                @fbartels Turned out that my original reporter was not a customer of Kopano but only used it for free, and as he also basically wanted free support from me and you while his company uses both of our work for free… weeel,… software development costs money.

                                My offer still stands to help resolve this even without a customer from our side, but it’s always a question of priorities. I fully understand that.

                                And yes this only affects outgoing mails. It’s related how Exchange converts Outlook’s MAPI to MIME and Kopano does this not exactly the same way.

                                Btw. as an additional workaround, I don’t know if its possible to use Kopano with SMTP in Outlook, but I think this should also work.

                                Best Regards,
                                Andre

                                  @aheinecke said in PGP Encrypted mail with Gpg4win and Kopano from Outlook:

                                  he also basically wanted free support from me and you while his company uses both of our work for free… weeel,… software development costs money.

                                  Yes, I was kind of expecting this already. Its kind of sad that if you make your software freely available, that people then also expect that your time to fix their own problems is free as well.

                                  Thanks again for your offer. I have reached out internally to check what we can do here.

                                  Yes, one workaround that I could imagine is indeed to configure an additional smtp account and use this one to send out mail. Another alternative would be to write the message instead with our WebApp and use https://www.mailvelope.com/en.
