Hmmm .... Unless I'm doing something wrong, it doesn't seem to work. It
always is reporting an error - even when using your own hostname:

  Looking up Reverse DNS for IP Adress: [ipadmin.junkemailfilter.com]
  ERROR - Reverse Lookup Failed for [ipadmin.junkemailfilter.com]

Ok, fair enough, ipadmin is just an alias:

  % host ipadmin.junkemailfilter.com
  ipadmin.junkemailfilter.com has address 69.50.231.167
  % host 69.50.231.167
  167.231.50.69.in-addr.arpa domain name pointer
smtp167.junkemailfilter.com.

So, then I try smtp167:

  Looking up Reverse DNS for IP Adress: [smtp167.junkemailfilter.com]
  ERROR - Reverse Lookup Failed for [smtp167.junkemailfilter.com]

        -Bill

P.S. You might also fix the spelling error: "Adress" -> "Address".
