I solved the problem by changing the primary DNS reference in MacTCP on that machine to refer to a different DNS than itself. QDNS Tech Support also identified a problem with the target email domain where the MX record was a CNAME to a CNAME to an Address, but the reverse lookup of the Address did not confirm the "A" record name. They thought changing the MX record to point directly to the address in the A record and fixing the in-addr.arpa reference to have the same name would have resolved it without changing the MacTCP DNS reference.
