Watch word blocking new email addresses

Watch word "email"
existing email address :
new address:

Sorry, we were unable to deliver your message to the following address.

550: X-Host-Lookup-Failed: Reverse DNS lookup does not match for

Also, if I activate watch words and try to send email to "different.username@spamgourmet",
I get a failure notice unless I add "different" to the watch words.
I thought watch words affected email address creation but it also appears to block existing email addresses that are not in the watch word list.

Any suggestions how to make watch words work?
What am I misunderstanding?

that error is different from what would happen with a watchword rejection (which wouldn't create and error, actually - it would quietly discard the message). That error indicates that one mail server in the chain does not have a properly configured domain name reverse lookup, and the next mail server in the chain (which could be the spamgourmet server) is refusing to talk to it because of that.
