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
