Trivially. I assume you're using Exim 4.xx - in which case look at the
verify= condition in the ACLs. For example
require verify = sender
requires that the sender address is verifiable. Verification makes use
of your router setup which means you can tailor it to your needs. For
more details see the ACL section in the spec - chapter 38.
