The problem with this is that the DNS returns the response (of the multiple PTR records) in no particular order, so looking up the rDNS can return one of three different names... # nslookup > set type=any > server ns4.msft.net. Default server: ns4.msft.net. Address: 207.46.66.126#53 > 212.115.107.131.in-addr.arpa Server: ns4.msft.net. Address: 207.46.66.126#53 212.115.107.131.in-addr.arpa name = mail1.microsoft.com. 212.115.107.131.in-addr.arpa name = smtp.microsoft.com. 212.115.107.131.in-addr.arpa name = maila.microsoft.com. > So, if I put: whitelist_from_rcvd [EMAIL PROTECTED] mail1.microsoft.com whitelist_from_rcvd [EMAIL PROTECTED] smtp.microsoft.com whitelist_from_rcvd [EMAIL PROTECTED] maila.microsoft.com will that work? Or will each command clobber the previous one? -Philip
