Just make sure they are truly dynamic ips. Many people block ips identified as "DSL" connections. Those are not necessarily dynamic ip based. My mail server runs on a business package dsl with 5 static ips. Not everyone can afford T1/T3 connections. As for getting a "real mail server", that would involve colo or getting a T1. My dsl package is only ~$50 a month. Much cheaper than colo and I can get physical access to the box whenever I want. SBC allocates separate class C's for dedicated customers. I'm sure its possible to distingish the two. As for the 550: Spammer message, that is definetely on the other end. Some anti-spam add-ons for mail servers automatically reject mail like this. In addition, admins often block specific domains or ip addresses manually in their config files. I have about 15 ips and domains in my sendmail config file because of repeat offenders who send spam or viruses.
