mconnect − connect to the SMTP server on a host
mconnect [ -version [ host [ port ] ] ]
mconnect connects vi IP prototocol -version (’-4’, ’6’) to port on host. It sends its input to host, adding a CR to each line. Meanwhile it prints anything it receives from host.
If -version is not supplied, mconnect uses by default IPv6.
If port is not supplied, mconnect uses port 25 (SMTP).
If host is not supplied, mconnect connects to the local host.
