Dave, As we've discussed here *many* times, the key reason for wanting to run your own SMTP servers is for control over your own mail, especially security and privacy. Given that most e-mail is still not encrypted at the user message level, the use of opportunistic encryption (such as STARTTLS) at the message transport layer is extremely useful. However, this requires direct server public connectivity, generally on port 25, not port 587. The use of third party servers for transiting e-mail (be they your own ISP's or outside services), while providing some conveniences and in some cases special features, still negates the key advantages of direct connectivity, particularly the privacy aspects. The choice of using these services (or not) should be up to the user, not dictated by arbitrary ISP policies. I won't get into the port 25 vs. spam vs. user control argument here yet again, other than to note my original "Tripoli" white paper from several years ago ( http://www.pfir.org/tripoli-overview ).
