Use nslookup. This is what to type in DOS or UNIX:
nslookup
set query=MX
domain.com.
The output should show the mail servers listed as the "mail exchanger". Make sure to
block all of them if there is more than one.

Subject: Tracking a site
Hello e'body...
I want to block ALL trafic from a particular site, including mail, http,
icmp, etc, etc...
I have their web server blocked, but I can't track their mail server to
block that IP, I've tried the obvious, like PING MAIL.DOMAIN.COM, or PING
SMTP.DOMAIN.COM, etc...
Any ideas?
