I have recreated the mailbox from scratch. So the error was gone for some days. However, the "Excessive errors processing email for" error comes back with some emails. I guess this issue is caused due to unwellformed emails comming in. All emails I have seen associated with this error are spam emails. If I delete the spam email directly in the mail box, the error is gone until a new email is causing this error.Here are details about the system:ostickt v1.7.3 with some mods.PHP Error log entries: Mail FetcherExcessive errors processing emails for mail.example.org/myeamil@example.org.
