DNS is not meant for that. At least, not the DNS itself. It is
something that goes under another tool, called GSLB (Global Site Load
Balancer). It will add/remove DNS records based on test availability.
It is something that is widely used on the Internet.

Quoting "Bauer, Stefan (IZLBW Extern)" <stefan.ba...@iz.bwl.de>:
Dear Developers/Users,
We want to load balance mails from the intranet to the
postfix-relayserver-farm for outgoing traffic.
Can we abuse A-records to load-balance in the same way MX-records
have been designed?
A relay.example.com 192.168.0.1
A relay.example.com 192.168.0.2
We want to have the client load-balance between the two servers. And
more important to skip to the second if
one is not available anymore.
Is this rfc compliant and can be seen as best practice?
Honestly speaking is this something an administrator should do? :)
Stefan
