It's irrelevant whether it's on dyndns or not. Relevant is whether the IP you are using has any reverse lookup at all. If the ISP you're using at the time doesn't have reverse lookup configured for your allocated IP, you're in trouble. Dyndns only provides a name->IP mapping, but not the reverse. My cable IP has reverse lookup and as far as I can tell, I never had a problem sending email via smtp directly, dyndns or not.
