How to find out if a host has an SMTP Server installed? Type
the following on the command-prompt: telnet host_name 25
If you get a response, then an SMTP server is installed and active on the host.
If you do not get a response, then either an SMTP server is not installed or the
SMTP server is inactive. Instead of host_name, you can also specify
the TCP/IP address of the host_name. |
