search for: login_max_logging_us

It appears that when running Dovecot as a proxy-only box with "login_process_per_connection = no", it ignores the value of login_max_logging_users. And in Linux, since each socket requires a file descriptor, if you don't increase the maximum number of open files that each process is allowed to have open, imap-login will reach the 1024 open file limit and start logging the following errors: imap-login: socket() failed: Too many open...

I tried to google about this problem but what I found were related to other processes such as imap etc. Thanks in advance for your help. -- Ceasar

Am I misunderstanding the config or is this expected behavior? login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_logging_users = 256 The mail server receives about 1.5 - 3 logins per second and usually has around 75 simultaneous IMAP sessions.
