According to http://wiki2.dovecot.org/LoginProcess
Since one login process can handle only one connection, the service's
process_limit setting limits the number of users that can be logging in
at the same time (defaults to default_process_limit=100).
I understood this as there can only be up to 100 (or 1000 in my case)
concurrently trying to log in, but once the user logs, the imap-login
process ends (starting corresponding imap processes) and another users
could log in. So there could be more than 100 users connected, but up to
100 trying to connect. Am I wrong?
If I am wrong, why in my system there is no imap-login processes (or
just a few) but a lot of imap?
