PROBLEM

The Pop2Exchange service keeps crashing. The reason might be related to a corrupt email on the Pop3 server.

Stop the Pop2Exchange service
Check the Pop2Exchange log files for each user configured
- Directory: ..\GFI\MailEssentials\AntiSpam\Debug Logs
The log file will be named:
- pop2exchange_mail@myemailaddress@mydomain.log
- Check the last modified file first, as this is the most likely to be the one with the problem
Check which email is being downloaded over and over again
This email is corrupted and cannot be downloaded, causing the service to stop when it tries to download the email
- Note: The email may have been sent to more then one user, or there may be multiple corrupt emails
Log into the Pop3 Server and delete the offending email
Restart the Pop2Exchange service
Wait 15 minutes to confirm issue is resolved

There is a corrupt email on the Pop3 server that cannot be downloaded properly.
