login_processes_count = 32

This means that Dovecot always keeps extra 32 login processes that don't
do anything else than wait for new connections. That's not at least
helping :)

Anyway, I'd like to get lsof of an imap-login process that is doing SSL
proxying. Unfortunately I don't think there's any simple way to know
what processes are doing that and what aren't. Setting
login_process_count=1 at least makes it more likely that you'll hit the
right process. If trussing the process shows that it's writing some
garbage to file descriptor 1, it's probably proxying SSL..
