I am trying to do an IMAP migration to our new Kerio Connect server, however it fails.
I have identified the issue. When the IMAP tool starts its migration, it attaches to the Kerio Connect Server and restarts (for whatever reason) the IMAP services. Whilst doing this - the service does not start as it says (according to error log) something else is listening on that port - which it is not.
To prove this - I logon to the Kerio Connect admin interface - open up services and right click on IMAP and select restart. It fails stating something else is probably listening on that port. I then right click IMAP service again - click 'start' and it starts.
I can confirm that there is nothing on that port at all.
I have tried:
changing IMAP listening to another port -same error
changing IMAP listening address from all to one IP - same error
changing mailserver.cfg IMAP section 'timeout' from 300 to 2400 - same error
It appears that the issue is that IMAP services is restarting TOO quickly - almost like it stops, but tries to start before itself has actually 'released' the port (if that makes sense).
My installation is a FRESH standalone Ubuntu 10.2 with all updates and latest Kerio Connect release.
I rang Kerio Technical support in Australia and they confirmed that this is a known issue on Linux boxes.
Surely, I can't be the only one this has happened too? Does anyone have a work around for this? I have 75 mailboxes to import !!
I'm having the same problem, I'm using Ubuntu 10.04 and Kerio Connect 7.4.1.
But I just re-run the KIMT program and started the IMAP-service manually. And now I'm just finished with a migration of 28 accounts and 250000+ mails without a problem.
But it is a strange error...
