No. It means that it disconnected a client that wasn't yet logged in because login_max_connections was reached. It should happen only if login_max_processes_count was reached. Perhaps there's still a bug somewhere in there.. How many imap-login processes do you have running? Increasing login_processes_count probably helps for now. > login_process_per_connection: no > login_max_connections: 32 With these settings it should have allowed 32*128 connections / ssl proxies until the connection queue full error would have happened.
