Hello,
today dovecot almost died again. Actually, the daemon was still running, but the daemon didn't reply with its greeting message after establishing a connection. I noticed two things that scare me: One dovecot-process was running with almost 100% load and there were two extreme users, one with more than 80 concurrent connections, the other one with about 50 connections.
The only way I found to limit connections was max_mail_processes. But this doesn't help very much. I'm looking for something like MAXPERIP as I find in courier-imap. I don't want to switch back to courier-imap because I cannot limit anything in dovecot.
Regards Marten
