is it possible with BIND to replace authoritative MX records with
internal gateways, so that the MTA can route the email to internal
gateways? Of course, sendmail/postfix provides a solution to do that.
But I am looking at DNS level, as follows:
;; QUESTION SECTION:
;gmail.com. IN MX
;; ANSWER SECTION:
gmail.com. 870 IN MX 10 localrelay1.example.com.
gmail.com. 870 IN MX 50 localrelay2.example.com
