I have implemented smtp_dns_reply_filter (currently, testing), which
matches a resource record against a (regular expression) pattern.
At the moment supports IGNORE, but it would not be difficult to
implement a REPLACE action. The content of the resource record have
been "valid-hostname" sanity checked, so there is little danger of
malicious substitutions.
Thus, Postfix could do
foo.example.com. 12345 IN MX 10 bar.example.com.
REPLACE foo.example.com. 12345 IN MX 10 baz.example.net.
Similar operations for A/AAAA records,with some limitations (can
change the last two fields only, not the fields that are determined
by the query itself).
Would that solve the problem?
