fetchmail repeated retrieval of emails
After upgrade (from 3.0.3.X to 184.108.40.206) we had an issue of a fetchmail setting that cause repeated retrieval (more than 20.000 mails) of the same emails.
The offending account had
- Delete emails after retrieval: NOT set
- Retrieve all emails (incl. read mails): set
This combination should be made illegal and on upgrade an appropriate action should be taken if the combination is encountered. I have not found out why this combination did not cause problems in the past, it surfaced only after upgrade to 220.127.116.11
