automx2 v2019.0

I have read that before writing the first line of code:

  [Server entries] may appear several times. They are in order of
  priority, the first entry should generally be used, unless there's
  a specific factor or policy which prefers a later config.

In RFC terms, SHOULD is not MUST, and one can always expect software to
not care about an issue when marked with "should". It would be nice if
automx2, at some point in the future, allowed specifying an order of
preference for servers, but since clients may not even bother honouring
that order, I see this as low priority.
