I think you answered your own question. There is some Postfix
misconfiguration that is creating some kind of retry loop when host
lookup fails. This is more of a Postfix question than a MailScanner
question. You need to examine your Postfix config and more than this one
log message to figure it out.
See <http://www.postfix.org/lists.html> for info on Postfix lists.
