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".
