      @modelnine,
      thank you yery much to make things clear. This is quite sad while imaps isn’t state of the art but many still use it.
      I’m wondering that there’s a major release upgrade and this isn’t working.

      Stupid me tested in a sandbox but I did not test the imaps function. I cannot go back to 8.7

      So I will wait for things coming.

        @fbartels is there any possibility of getting one of the two patchsets (or both) which are now in my Github-tree into Kopano some time soon? ;-) Basically, as it stands, for 9.0 and 8.7, (at least) all server-side SSL is currently broken. Thanks!

            @TomSchmidt: I use stunnel to have imaps as long as kopano-gateway fails to provide imaps.

              Hi, nice idea, but I have to connect two Thunderbird-Users and TB can’t use z-push as AcitveSync. The addons promising ActiveSync are crap. One of them is my Mom using Win10. So this idea crashes here :-)

              But thank a lot for replying!

                @TomSchmidt stunnel is like a proxy or SSL-wrapper. With stunnel iprovide imaps with kopano-gateway to connect my TB-users.
                ActiveSync has not too much to do with that.

                  OK, I got it, was on a wrong journey. I did the same and it works perfectly.

                  Thanks!

                    Hello @modelnine,
                    it looks like recent refactorings to HrEnableTLS, HrSetCtx and related are causing issues:
                    I’m getting SIGSEVs on SSL_accept (using openSSL 1.0.1e) , similar problems are discussed here.

                    Reverting commits introduced by PR22 fixes the issues on my unsupported system (CentOS6).

                      Hi guys,

                      What is the status against kopano-gateway in Debian 10?

                      We have experienced also same problem (many times in a hour; autorestart works partly):

                      Tue Feb 25 14:19:07 2020: [ZGateway IMAPs|T542] [crit ] #20. /lib/x86_64-linux-gnu/libc.so.6(clone+0x3f) [0x7f243aa8b4cf]
                      Tue Feb 25 14:19:07 2020: [ZGateway IMAPs|T542] [crit ] Signal errno: Success, signal code: 1

                      in kopano-gateway 8.7.0-3 (comes from Debian buster main section)

                      What should I do - downgrade system to Debian stretch/9 and use some supported kopano-core (and kopano-gateway) version or is there somewhere working kopano-core/gateway system against Debian 10 already?

                      All we know that Debian 9 is already old-stable. So better solution might be Ubuntu 18.04 then?

                      (sorry - maybe there is a better thread…)

                      /Mikko

                        The status is that all is in good order in the source codes as of Feb 1 2020, corresponding to v9.0.3 and v10.0.1.
