I suspect this is that the receiving server couldn't find either a 
reverse lookup or an MX record for the sending server. Alot of mail 
servers will reject mail from a machine that doesn't have a reverse 
lookup or an MX record. Usually, if there isn't an MX record, it will 
complain about it being an "Unroutable domain". This is for the sending 
machine mind you, and has nothing to do with the addressees in the email.
