A BUGNOTE has been added to this bug. ====================================================================== http://www.dbmail.org/mantis/bug_view_advanced_page.php?bug_id=0000221 ====================================================================== Reported By: xing Assigned To: ====================================================================== Project: DBMail Bug ID: 221 Category: POP3 daemon Reproducibility: always Severity: feature Priority: normal Status: new ====================================================================== Date Submitted: 21-Jun-05 16:44 CEST Last Modified: 21-Jun-05 21:28 CEST ====================================================================== Summary: POP3 daemon can't connect to mysql but dbmail-smtp injects emails fine.. Description: After upgrading to 2.1.1, dbmail-smtp injects emails just fine but pop3 and imap daemon both chockes on init. Apparently the init db check fails breaking the startup. Since dbmail-smtp and dbmail-pop3d both use the same config/libraries, not sure why the db check fails.

All daemons share the same framework. The parent process (20977) preforks and goes into a main event-loop which checks the database connection every 10 seconds or so. If the database is down, all preforked children are shutdown until the database comes back; then they are preforked again and we're a happy family of processes. You say dbmail-pop3d chokes, but I see no signs of failure other than a problem with the database connection. I need more info...
