Again, your provider should contact them to get this fixed. Please
don't forget that Internet mail is a priviledge, not a right. There
are many sites blocking based on domain endings (*.tw, *.cn), on so
called "rogue networks" (all AOL IPs except their MXes), others block
their customers port 25 (AOL, Earthlink) or redirect it to their own
SMTP server, no matter which one you wanted to connect to and so on.
It's about fair play. If I choose to operate a mail server that does
not need to take direct delivered eMails from declared dialin ports,
no matter if this is modem, ISDN, DSL, short wave, CB or anything,
then that's up to me, and perhaps my customers. I've seen many site,
including ISPs with millions of customers(!) implementing these
blockings. If you have a static IP, which is IMHO the only one suited
to provide "real" server services, then your provider should be able
to adjust the PTR DNS record so you don't fall into the dial-up pools.

Cheers,
 Johannes                            mailto:[EMAIL PROTECTED]
