mjpuczko 0 Posted February 6, 2003 Quote: Port 23 for telnet Port 25 for SMTP 23? i was told 25. i even went into ms-dos (on a win2k pc) and typed 'telnet', then 'open IPAddress 25' where 25 is the port to open & it worked. got that info from microsoft.com Share this post Link to post
DS3Circuit 0 Posted February 7, 2003 3 com firewall ... heh didnt know that was still supported All of 3coms netbuilders and corebuilders have been discontinued for over 2 years. You can telnet into 25 for debugging your SMTP connectors ... like checking for open relay and so on .... Share this post Link to post
