does asterisk do it that way or does it look up the first A record it
gets and use that and only that ??  If that is the case, and it does not
even support MX records then the correct answer would probably be closer
to "asterisk does not do that". 

I really dont know but if I had to guess I would say that its not using
MX records, because it wants a smtp server, and given the way other
things in asterisk are done its likely that it does not try a secondary
A record if the primary is down.

You can still trick asterisk by using something similar to
ultramonkey.org (although you may not have to go quite as far as
ultramonkey would take you) so that asterisk thinks its just connecting
to a single host all the time, and if it fails its transparently
switched to the backup system.

Of course a more elegant solution would be, assuming its not there which
is an assumption I did make, to add the functionality to try multiple
hosts in order until it gets something resembling a success code (2xx,
usually 200), and if it runs out of hosts then queue and schedule an
event to try again in some timeout interval until the queue is empty.
But hey, for all I know it already does this, I really havent looked and
barely read the posts in this thread.
