mconnect(1M)

mconnect -- connect to SMTP mail server socket

Synopsis

telnet host 25

Description

On SCO OpenServer, the mconnect command opens a connection to the mail server on a given host, so that it can be tested independently of all other mail software. While this command is not provided on UnixWare, the same result can be obtained by using the telnet command as shown above. Replace host with the name of the mail server host, or localhost to make a connection to the mail server on your local system.

The server at the other end of the connection expects any communication over this connection to conform to the Simple Mail Transfer Protocol (SMTP). Terminate the connection using the quit command (typing an end-of-file causes an end of file to be sent to the server; an interrupt closes the connection immediately and exits).
