My mail server had been working for 3 months without a hickup. About 2 weeks ago I had to restart my IMAP daemon because it had stopped.  A week later I had to do it again.  Now IMAP crashes immediately upon start.  I am unable to access my old emails so I cannot just change imap servers unless there is one that uses Maildir.  I uninstalled and reinstalled courier imap.

I cannot find any logs with information about the crash.

After starting imap I run telnet localhost 143 and I get.
Connected to localhost.
Escape character is '^]'.
Connection closed by foreign host.

Courier POP3 works just fine so I am pretty sure the issue is with imap.

Thanks for your help
