The spam has been so bad from residential block IPs that most ISPs do 
not accept them any more (they know the IP blocks that are residential 
vs. "real' mail servers).  Regardless of the IP mapping back, mx 
records, etc.  I'm rather sure this is your problem although you've not 
given enough details to know for sure.  If you are paying your ISP for 
a business connection they should have put you in a different IP block, 
one that is more likely to be "trusted".

If you relay your outgoing mail through your ISPs outgoing mail 
(authenticating) it should be acceptable almost anywhere, unless they 
are sending a lot of spam out.

There's info out there about how to do this for sendmail, postfix, 
whatever you are using.  I think postfix is a lot easier.

HTH.
