They do have a naming convention that makes sense to them. But if the AOL intent is to force mail servers to use rDNS entries that can be traced to the source for prosecution of spam/virus senders, then the following entry does allow the identification for that purpose:
las-DSL224-cust089.mpowercom.net The RFC (and commonly accepted practice) is to require an rDNS entry, presumably for IP owner identification purposes. This rDNS does that, even though it contains the three letters "DSL". I would say that AOL is lazy and sloppy: They are "dumping" millions of messages b/c they might be spam. In the process they are "dumping" many good messages which the users expect to receive. But then one might say that the AOL users are lazy and sloppy: They are getting what they pay for, which is lousy service and the guarantee that "most" of their messages will make it through. They have been educated by AOL that this is OK. If we assume that AOL users don't mind "loosing" messages from "some" sources, then AOL users won't mind when they don't get messages from our users. But when AOL users complain to my users that they can't receive messages from us, then AOL has pushed a tech support issue onto me, costing me time/money for a policy decision that AOL has made. Maybe I should buy AOL stock!! When a business plan!! Have everyone else do your support for you.

If I put equipment on my network here (at AOL) then it better be named right in both forward and reverse lookups. When using generic rDNS for blocks of things I at least take the time to make sure I don't name something a name that it is not. Doesn't it make things difficult for troubleshooting when you have sloppy naming of interfaces? -Josh To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/ --- [This E-mail scanned for viruses by Declude Virus (http://www.declude.com)] --- [This E-mail scanned for viruses by Declude Virus (http://www.declude.com)] To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
