maybe something has changed on the server or your client
settings and you are using a non-supported auth mechanism

usually you can telnet to a IMAP server and look at the
banner what is supported

[harry at srv-rhsoft:~]$ telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK [CAPABILITY IMAP4 IMAP4rev1 ACL RIGHTS=texk NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE
STARTTLS AUTH=CRAM-MD5 AUTH=DIGEST-MD5 AUTH=PLAIN AUTH=LOGIN]
