Hi,

lets say dovcot should serve 1000 user (only imaps) without rejecting a users connection because of to short resources. With version 1.x I had to increase login_max_processes_count = ...

With 2.x I'm not sure which parameters I have to set. So Thunderbird 3.x has a default value of 5 connections to cache. "dovadm who" shows quite often 5 connections:

userx 5 imap (11154 11152 11158 11156 11150) ...

So dovecot has to be configured for 5000 connections/imap-login's?

Within 10-master.conf these defaults are shown #default_process_limit = 100 #default_client_limit = 1000

Is it right process_limit is not generally a problem because oldest imap-login process(?) will be closed? (With this expected number of users this value should be increased too.)

But what about client_limit? Does it has to be increased to 5000?

(There have been some hints by Timo concerning "doveconf -a service" to see how limits will be used for different services.)

Any advices? thanks
