When a Mac OS X "Mail.app" client POP's in for mail, I always get an error
log message like this:
vchkpw-pop3: password fail (pass: 'd502e3b49fb33d7f7d419d469b51a5a0') <EMAIL
ADDRESS>:<IP ADDRESS>
Have them launch Mail.app, go into "Preferences", select "Accounts", go to the "Advanced" tab and check the "Authentication" popup. I'm able to use MD5 Challenge-Response or Password on my system. See if they have it set to one of the Kerberos options. Or, if it's set to MD5, have them try Password.
