Sorry for the ignorance here... When you buy wholesale dialup how does the internet-destined traffic get routed from your customer to the internet. If it goes from the dialup through the wholesaler's network to yours and to the internet, this will not cause breakage (I doubt this is the case). If it goes from the dialup through the wholesaler's network and directly to the internet, this WILL cause breakage. (I can think of some uses for policy routing here, but I doubt that in most cases they would be useful) The point of the well-known addresses is to provide a best-guess default for those services which most likely need to be utilized from the dialup provider. For example, a lot of ISP's will not provide POP before SMTP authorization for relay, instead they rely on whichever ISP is actually hosting their "roaming" customer for relay. If ISP's could configure their customer's computer so that as long as they dial into a RFCXXXX compliant ISP they will be able to send mail, it would be great. I do understand that there is going to be some breakage. Especially when your customers don't dial into you. That's when having them hard-configure their software for your servers and having them use POP before SMTP auth makes since. - Forrest W.
