i would say such MX is invalid and should be ignored the dot at the end normally defines a full-qualified name which is not true in the example and AFAIK MX-Records normally will not be expanded from a client means: "host2 CNAME host1" * "dig CNAME host2" gives no answer, even with dns-suffix * "dig CNAME host2.domain.tld" is completed by the nameserver
