Yes, I currently have "protocols = pop3 pop3s". I am using xinetd to start pop3-login because I have a VPS not a dedicated server and I am trying to conserve memory usage. Eventually, I will start also start imap-login via xinetd and will add those protocols (protocols = imap imaps pop3 pop3s).

the memory usage of those "login" processes is pretty low and you get limit the number of workers (login_processes_count in the config). that said your xinetd doesnt gain you much.

Thanks. That is a good point. Sounds like "login_processes_count=1" is the thing to do.
