Problem With Exchange Server - HELO and DNS MX Settings

By rui.b.rodrigues ·
I administrate a server with windows sbs 2003 premium for 80 users. In this server is running a exchange server.
When some users send email wiich domain is in the same ISP that I, it comes back with the following message:
< #5.7.1 smtp;550 5.7.1>: Recipient address rejected: Mail appeared to be SPAM or forged. Ask your Mail/DNS-Administrator to correct HELO and DNS MX settings or to get removed from DNSBLs; MTA helo:, MTA hostname:[My-IP] (helo/hostname mismatch).
I read some articles about the error 550 5.7.1 in MS but still having no clue what so ever how to resolve the problem.
