That makes no sense whatsoever. Just put an appropriately quick retry
rule on mail.123.com - you aren't going to normally find it fails once
and then immediately works unless you have a broken network, and
patching application s/w is not the right way to deal with that.
An alternative approach might be to tie multiple IP addresses to
mail.123.com - exim will try all of those.
Anyhow, the MX specs say that exim *must* not deliver to
>> >> 123.com preference = 20, mail exchanger = mail.123.com
if the current host is
>> >> 123.com preference = 20, mail exchanger = relay.mydomain.com
since bouncing mail between equally prefered MXes is a mail loop and a
bad thing(tm).
