Ah.

I guess you'll need two, just like you need two ACL statements.

r1:
driver = accept
domains = +local_domains


r2:
  driver = accept
  domains = +localmx_domains
  condition = ${if match_domain \
                {${if match{${lookup dnsdb{mx=$domain}}\
                  {^\N\d+\s+(\S+)\N}{$1}}}\
                {+localmx_domains}{yes}{no}}


Oh, no. That won't work, I'm afraid. There's no guarantee that the MX
records will be returned in order. If you happen to know the preference
value for the primary MX records, you could match on that. Suppose it is
10:

r2:
  driver = accept
  domains = +localmx_domains
  condition = ${if match_domain \
                {${if match{${lookup dnsdb{mx=$domain}}\
                  {\N10\s+(\S+)\N}{$1}}}\
                {+localmx_domains}{yes}{no}}

Comments are your friend. :-)
