On the first set up page of Zimbra Desktop I am trying to connect to my own IMAP account on our server which uses Courier MTA (Courier-IMAP 4.2.1/i386-sun-solaris2).
I receive an error from Zimbra Desktop:
Service error. Please check your server settings; verify your email address, password or IMAP access (if required).
When I check the courier log on the server where the email is stored I can see the error message:
couriertls: accept: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
Looks like our mail server is not compatable in some way with Zimbra desktop software. I don't use SSL for any of the connections and just connect via standard ports 143 and 25.
The account works fine with Mozilla Thunderbird and I am positive I have entered the setting corretly.
Anyone have any ideas?
