How to find out which mail server my host is set for me?

Question

I am using the MediaTemple (dv) service. How to determine which mail server is installed? Should I use a shell? If so, which command will be used?

Answer 1

Go to the shell and enter the following command:

telnet <hostname> 25

This will return with a line like this:

220 example.com ESMTP Exim 4.69 Thu, 13 Nov 2008 10:06:01 +1100

as you can see, EXIM runs on this server. A.

Then enter QUIT to exit back to the shell.

UPDATE: . Some hosts use a different address for their mail server, if you are on Linux, you can enter the following command to get a list of mail servers for this domain:

dig -t MX example.com

Answer 2

Try

$ nmap -p 25 -A -T polite <hostname>

Linux- nmap.
