Can't log into IMAP but pop3 works

[J. Pilfold-Bagwell]

Hi All,

I have a problem where I can log into cyrus using POP3 but can't with 
imap. Telnet sessions return the following:

sysadmin at smbserver:~$ telnet localhost 110
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
+OK smbserver Cyrus POP3 v2.2.13-Debian-2.2.13-13ubuntu3 server ready 
<545339973.1247349499 at smbserver>
quit
+OK
Connection closed by foreign host.


sysadmin at smbserver:~$ telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.

    delprune    cmd="/usr/sbin/cyr_expire -E 3" at=0401

}


Aside from this it works fine. Mail gets delivered to mailboxes etc. 
just can't use imap.

Thanks,
