RE: dig command for reverse dsn check
another method ;-)
use the 'host' command with either the domainname or the ip
dle:demo:/etc {101} # host yahoo.com
yahoo.com has address 66.218.71.198
yahoo.com has address 64.58.79.230
yahoo.com mail is handled (pri=1) by mx2.mail.yahoo.com
yahoo.com mail is handled (pri=5) by mx4.mail.yahoo.com
yahoo.com mail is handled (pri=1) by mx1.mail.yahoo.com
dle:demo:/etc {102} # host 64.58.79.230
230.79.58.64.IN-ADDR.ARPA domain name pointer w1.rc.vip.dcx.yahoo.com

The ip address of the domain name or the email server? use dig to find the IP address of your host (dig foo.bar) use the IP address that comes back in the ANSWER section for the dig -x (IP address from above) PTR again, look under the ANSWER section, and it will show you the reverse record.
