That does indeed resolve the issue, so do you think this is a Cyrus SASL 
problem or a Cyrus IMAP (POP) problem?

Also, do you have the same -p option specified? I'm wondering if others 
are experiencing the same problem - all of our servers are on the same 
version of cyrus 2.3.7 (from RHEL) or older and seem to exhibit the same 
behavior.
