Then AOL will not accept mail from them, because the reverse name doesn't match the forward name. The correct fix for this is to use BIND 8 and DDNS to update the DNS contents from the radiusd. Unlike DDNS used by the customer's machine, you can trust your own radiusd. This also works well for assigning dynamic rather than static IP's. Note that if you buy your POP's from places like PSINet, which doesn't reverse the IP to you, then AOL will reject them completely based on the IP reverse matching a PSINet dialup. Basically, this is a consequence of PSINet not enforcing their AUP (Acceptable Use Policy). For ISP's that have customers running on these things, and for which they enforce their own AUP, and for which the customers can easily be vouchsafed by the ISP, the ISP must run a mail server which the their clients can designate as a "smarter host". Arguably, the client machine shouldn't have to use the smarter host all the time, but AOL returns a 5xx error instead of a 4xx error, so a error message relay queuing policy would be totally ineffective. EarthLink is one ISP that has the PSINet POP problem with mail that their customers send to AOL; EarthLink has to run a relay for these customers (or decide to buy their POP's from some place else).
