           Summary: Long timeout when checking SSL capabilities
           Product: kmail
           Version: 1.9.52
          Platform: Compiled Sources
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: fhimpe pandora be


Version:           1.9.52 (using Devel)
Installed from:    Compiled sources

When I start kmail for the first time, a wizard pops-up, asking me for my e-mail address and (after choosing IMAP) in a second stap asking the addresses of my incoming and outgoing mail servers. After entering that, a message appears that it is checking the security capabilities of the server, and it hangs for a long time (at least one minute), without any more feedback. It feels like kmail is in an endless loop. Only after some time, kmail comes alive again.

Debug messages before the hang:

Ports 465 and 993 are closed on my mail host (but not filtered).

I guess some connection time-out is currently too long.

This seems similar to bug #131843 but that bug is supposed to be fixed.
