Have a strange problem with just POP3 users. Their email clients will fail every so often with the following:
Logging into POP Server, PASS [09:16:29 PM]
There has been an error transferring your mail. I said PASS
This example is from a Eudora client, but same things happen with Thunderbird and Outlook.
Here are logs. This user has his client checking every 10 minutes. First log entry here is last good one before it fails:

Everything went fine here, then the next auth attempt fails:
