Hi Tonino, > Courier pop3d is run directly by courier, as a daemon, and (as long as > I know) cannot be run using tcpserver.
That's not true; actually Courier-IMAP starts the "pop3login <authlibmodules> pop3d" chain under couriertcpd, which can be replaced by tcpserver, if you want to. It is not a daemon; couriertcpd is the daemon (like tcpserver). Jonas
