a) Exclude the domain from reject_unknown_recipient_domain.
/etc/postfix/main.cf:
smtpd_recipient_restrictions =
...
pcre:/etc/postfix/recipient-access.pcre
...
/etc/postfix/recipient-access.pcre:
/^example\.com$/ dunno
/./ reject_unknown_recipient_domain
b) Don't use reject_unknown_recipient_domain, or any feature that
may look up NS or MX records.
