No, he IS right. The issue is that while the mail RFC's don't require rDNS, there are a -few- rather stupid anti-spam filters out there that do. As long as you (or one of your users) is not e-mailing to someone on one of these mailservers your fine. But if you are, your screwed. We often get this kind of complaint call from customers who have setup this kind of deal and -1- person in their organization has -1- coorespondent they keep getting their mail rejected from. When we tell them they have to pay their ISP more money for a static IP address, whether they do it or not is usually dependent on how important the particular employee is, who is being screwed over.
