You're right, that one works. Now suppose that, instead of santronics.com, you were santronics.homestead.fl.us (domains of this form do exist). The query for SUBDOMAINS.santronics.homestead._ssp.fl.us wouldn't yield the desired result. Steve overstated his case when he said it would not work at all, but it does not work in general. -Jim _______________________________________________ NOTE WELL: This list operates according to http://mipassoc.org/dkim/ietf-list-rules.html
