MCONNECT(8) System Manager's Manual MCONNECT(8)
mconnect - connect to SMTP mail server socket
/usr/etc/mconnect [ -p port ] [ -r ] [ hostname ]
mconnect opens a connection to the mail server on a given host, so that
it can be tested independently of all other mail software. If no host
is given, the connection is made to the local host. Servers expect to
speak the Simple Mail Transfer Protocol (SMTP) on this connection.
Exit by typing the quit command. Typing EOF will send an end of file
to the server. An interrupt closes the connection immediately and
Specify the port number instead of the default SMTP port (number
25) as the next argument.
-r ``Raw'' mode: disable the default line buffering and input han-
dling. This gives you a similar effect as telnet to port num-
ber 25, not very useful.
