I agree whole heartedly that it "should just work" but time and time
again we have see where it does not work.

That would work if I was looking to use a specific IP address but
would like to use a specific host name. For example I would like
all mail outbound to example.com to bypass the DNS/MX entry of
mail.example.com and use instead backupmx.isp.com not just the IP
Address of backupmx.isp.com.
Thanks muchly for your suggestion.
