Usually this error message actually refers to the domain name in the HELO of the SMTP connection, it has to match the DNS PTR record for the ip address of the interface the mail is coming from. This is a blatant violation of the RFC 822 which specifically says that the receiving end must not require this. But you should check all your DNS servers and make sure they all have PTR records that match the information your MTA is using. -- greg
