ok, the message sandy sent, had a link that was claiming a problem on that domain with PTR/reverse dns, but if i reverse the address for the imail server 209.164.24.158.. i get a perfectly good reverse lookup from several outside dns servers.. my problem must be with something else.. i'll keep looking at the other warnings.
