A NOTE has been added to this issue. ====================================================================== http://dbmail.org/mantis/view.php?id=852 ====================================================================== Reported By: only-victor Assigned To: ====================================================================== Project: DBMail Issue ID: 852 Category: IMAP daemon Reproducibility: always Severity: major Priority: normal Status: new target: ====================================================================== Date Submitted: 14-Jul-10 15:14 CEST Last Modified: 14-Jul-10 21:21 CEST ====================================================================== Summary: IMAPD uses 100% CPU if some file was attached to mail Description: If I send mail without attached files, then all work well. But if I attach file which size about 2M or more, then dbmail-imapd uses 100% CPU and works long time. But postgres uses 0-1% CPU and loads about 2-3 seconds. After I accept message. I tried different mail clients and result the same. I have only 2 mail accounts at postgres database and about 10-20 mail messages.
