We cannot get a telnet connection to the IMAP port or a openssl connection to the IMAPS port. Kill -HUP of the dovecot server solves the problem. But again, when the usage increases, the problem surfaces again. There is no problem with POP or POPS. It continues to function normally while IMAP times out and freezes two or three times a day.
How many imap-login processes do you have at those times? See if changing login_* settings helps. http://wiki.dovecot.org/LoginProcess
