Subject: get rid of DNS ANY query

UltraDNS started blocking UDP-ANY queries so this is a problem.
This will disable domain canonicalization of the envelope address
of outgoing messages. This is as specified by RFC 1123 section 5.2.2.
However this requirement is obsolete and modern MTAs have disabled it
too.
