Rewrite/Override QTYPE with RPZ

[Tom]

I mean the other way:

My feeded RPZ blocks othercompany.com and *.othercompany.com. Therefore 
any qtype (MX, A, AAAA...) are blocked for this domain. Is there a way 
with BIND just to whitelist the MX for othercompany.com and the 
consequent A-Record (ex. mail.othercompany.com) that we are able to send 
mail to othercompany.com?

They'll also check things like dkim or spf TXT records.   If they don't like what they find they'll simply reject email even if you haven't been blacklisted.

Of course you'd have to make additional changes for the PTR, A/AAAA and TXT records for the new IP you select.

These often occur because the customer no longer has the email address they originally gave you (or they had a typo in what they gave you).
