I completely agree with Serge with respect to list vs collection. His comments are, in fact, not open to disagreement. They are technical facts.
However, I wonder if it might not be better to use a SortedSet to hold the MX records. Are we certain that returning a correctly ordered list is actually in the DNS server's contract? (Rather than just happening to be the behaviour of the ones we test against?) If we use SortedSet, with a custom Comparator, we can guarantee the correct ordering ourselves. If the DNS rfc states that the ordering MUST be correct (not SHOULD or MAY) then a java.util.List is fine. Otherwise I believe that a java.util.SortedSet is required.
