dovecot - Jun 2008 - Requested CRAM-MD5 scheme, but we have only MD5-CRYPT

After upgrading my dovecot installation about a month ago, I have started 
seeing "Requested CRAM-MD5 scheme, but we have only MD5-CRYPT" message
from dovecot in my logs.

Any help in finding and correcting the cause will be greatly appreciated.

CRAM-MD5 authentication can't be used with MD5-CRYPT passwords. See
http://wiki.dovecot.org/Authentication/Mechanisms
  and http://wiki.dovecot.org/Authentication/PasswordSchemes

Okay, so tell me something I don't already know. This system has run just 
fine for over a year, and then all of a sudden I start getting these 
warning messages. I have made NO changes to any system configuration. The 
only changes that correspond to when the messages started to appear are 1) 
I updated version of dovecot, and 2) I added a new user.
