This sounds like a mail server issue and not DNS specifically (since you
said "from").
As an example, with postfix, you could use sender_dependent_relayhost_maps
to define a database that maps sender domains to desired mail exchangers
to use.
(Also with postfix, the transport database can do mapping to override MX
lookups and choose transport type, like smtp, and also port numbers to
use.)
