Being limited to dynamic IP does not make you, or your server, a 'bad person'.
It DOES make it very difficult for the rest of the world to for-sure separate
your server from millions of infected PC's that *are* bad.
So - no emotion involved, but we could be blocking you on several counts:
- missing PTR record
- 'known' dynamic IP
- any of several public RBL's, dynamic IP or otherwise.
- part of a /24 block on your entire upstream.
- mere use of DynDNS
(who may not have planned it so, but are of a class of services that have been
abused by spammers).
Best thing for the short-term is to find a sympathetic relay host.
