What do you mean? That you have this?
MX 10 mail
mail A aaa.bbb.ccc.ddd
mail A sss.ttt.uuu.vvv

In my view, it should be done by our DNS lookup code. See RFC 2821, section
5:
The destination host (perhaps taken from the preferred MX record) may
be multihomed, in which case the domain name resolver will return a
list of alternative IP addresses. It is the responsibility of the
domain name resolver interface to have ordered this list by
decreasing preference if necessary, and SMTP MUST try them in the
order presented.
So it is handling a multihomed destination that needs to be addressed.
