Connecting to Zimbra over SSL

Reported by Justin Levens | July 27th, 2015 @ 05:09 PM

I am attempting to connect to our department's Zimbra server, however, I am receiving an '(unavailable)' message next to the mailbox. Mac Mail is able to retrieve messages. The logs from the Activity Viewer can be seen here: http://cl.ly/text/440w3L3n2t46/20150727MailMateLogs.txt

I tried using a similar configuration as Mac Mail which is using port 143 which you can see in the logs, then I tried using port 443 which is what my admin said to use. It was working fine on Friday, but the Zimbra server was updated over the weekend and is now running Zimbra 8.6.0_GA_1178 (build 20150618170638).

    If 143 works with Apple Mail then it should also work in MailMate. The problem seems to be the SSL handshake. Do you have SSL enabled in Apple Mail?

    You should not use port 443 since this an https port and not for IMAP, but you can try to see if port 993 works.

    You can try temporarily disabling SSL on port 143 in MailMate to see if this is the only problem.

    Ah, thanks for finding that link. Unfortunately that issue is still the same. I haven't changed MailMate to use the Apple framework.

    There is little I can do other than promise to contact you when/if this changes, e.g., by updating this ticket.

    Yes, then it's not the same issue. Could you provide me with the server address if it's accessible from the outside? I don't need to login I just need to be able to try connecting to the server. You can send it via “Help ▸ Send Feedback” (if you have a working SMTP server).

    Sorry about the late response. I get the same error if I try connecting to the server manually:

    > openssl s_client -connect mail.xxx.edu:993
    20296:error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol:/SourceCache/OpenSSL098/OpenSSL098-52.40.1/src/ssl/s23_clnt.c:618:

    I've tried various command line arguments for openssl, but with no luck. Since I'm using openssl within MailMate then it's unlikely I can make it work :-(

    The best I can do is to notify you when/if I replace openssl (if that's part of the problem).
