Good. >However, using a couple of reverse dns tests..it does not resolve. Bad. >Do I need to have something in MY dns server, where the domain is defined in >order for reverse dns to work? Maybe. If you asked your upstream "Please set up reverse DNS entries for my IPs", then you don't have to do anything (they would add the reverse DNS entries to their DNS servers). If you asked them "Please delegate the reverse DNS for my IPs to the following nameservers: ns1.example.com and ns2.example.com", then you would need to make sure that those DNS servers had the reverse DNS entries listed in them. > For example, something pointing to my upstram >providers name server as the place to look for reverse records? No. You don't need to do that, because nobody will get to your nameservers unless your upstream provider points them to you. >Also, I can I check the name server the reverse dns is suppose to be set up >in..using a nsookup type tool that would show the appropriate reverse >record? If you use the Reverse DNS Lookup at http://www.DNSstuff.com , it will show you how the reverse DNS lookup is performed, and whether or not the reverse DNS entry exists. If it doesn't exist, it will show you who is at fault (IE that your ISP's nameservers don't have you listed, or that your DNS servers don't have the reverse DNS entries). -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
