There is no RFC requirement for hostnames = PTR records, let alone PTR records at all. Some RBLs and ISPs do check for a basic PTR though, as a spam check technique. e.g. AOL, and will reject if none are found. (I believe AOL alone has a customer base of 6 times the total population of beautiful Slovenia):)) Here, (the US), they usually charge extra for that, a matching hostname to PTR, but it is meaningless if one has multiple domains. Hence the birth of SPF for spam checking. I still contend that most of the ISPs do block SMTP outbound now.. including the largest in the world AOL, along with Comcast, Earthlink, just to name a few. There are also several in Europe, the largest being GMX, Tuscali, etc. A few now have gone to SMTP auth even on their own servers. -- Gary ________________________________________________________ Current beta is 3.51.10 | 'Using TBBETA' information: http://www.silverstones.com/thebat/TBUDLInfo.html IMPORTANT: To register as a Beta tester, use this link first - http://www.ritlabs.com/en/partners/testers/
