So, your criteria for determining if you should do callout or not is what, exactly? The lowest (numerical) preference MX record? If that's the case, you could put a condition in your ACL statement before the verify = recipient/callout... using a dnsdb lookup, as described at: http://www.exim.org/exim-html-4.63/doc/html/spec_html/ch09.html#SECTdnsdb You'd need to do some regex matching or something to determine which one was the lowest pref MX, unless you would be satisfied enough just to check that your primary mail server is somewhere in the results, in which case it would be somewhat easier. It's going to be a chunk of extra overhead to be doing these DNS queries all the time, of course, but assuming your local resolver caches them, it shouldn't be too bad.
