[Dovecot] Split number of imap-login and pop3-login processes
Hi All,
Is there a way to define the number for imap-login processes and pop3-login processes separately?
My mail server is getting more IMAP clients and much less POP3 clients these days and it continues to run out of authentication processes. I have been increasing login_max_processes_count the last couple of days and I noticed that it's split between IMAP and POP3. All 129 imap-login processes are tied up while there are only 3 of the 129 pop3-login processes in use.
Any help would be greatly appreciated!
Thanx!!
Mischa

You can probably put the settings inside protocol pop3 {} and protocol imap {}. But maybe you should switch to high-performance mode: http://wiki.dovecot.org/LoginProcess
