Excerpt from L.D. Best: >Invoke telnet, hit ALT-A to start a session, then give it the URL for >mail you are trying to reach ... the one in your config file for POP3.

Your ISP may >vary, so you can experiment. If you don't specify the port, telnet has no way of knowing the port should be 110. Default port for telnet is 23, which wouldn't work for SMTP, POP3 or NNTP.
