Hi, I installed Dovecot on FreeBSD 4-STABLE machine and have a problem. MTA is postfix delivering to ~/Maildir, runs perfectly. Dovecot is configured to use plaintext auth, config file is at the end of this mail. When trying to get mail via IMAP, I'm getting the following errors: /var/log/dovecot.log > Aug 24 12:00:35 Info: Dovecot starting up > Aug 24 12:00:51 Info: Login: goshik

While working on a new test of what happens when the server goes away while commands are in flight, I managed to hit a race where I hit death from SIGPIPE instead of a clean transition to the DEAD state. I also found myself wanting to use nbd_poll from the test, but with a way to distinguish between the state machine progressing vs. hanging. Eric Blake (2): socket: Avoid SIGPIPE where possible

Dear All, I constantly encounter 'dovecot-auth', 'login-imap', 'login-pop3' and 'imap' processes consume 100% CPU. I run 'ps' and found those hanged up processes were running for a long time. I am wondering whether dovecot.conf has some configuration parameters that timeout those processes (or kill those after certain period of time). I am using dovecot
