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.

A 'real' one - not a dynDNS kludge.
