Starting imap4d

imap4d may run either in standalone or in inetd operation modes. When run in "standalone" mode, the server disconnects from the terminal and runs as a daemon, forking a child for each new connection.

The "inetd" mode allows to start the server from /etc/inetd.conf file. This is the default operation mode.
