With a DNS CNAME you cant have *any* other type of information associated. Period, despite some broken (MSgrumble) implementations that allow things like an MX and a CNAME to exist, it just doesn't work. :) Use an A line pointing to the other host in addition to the MX. That should solve you hairball. On Wed, 21 Jun 2000, John R.
