We're doing DNS lookups for inbound and outbound mail [there's not a lot
of it, so it's not much of a performance hit].
One domain responsible for much of the mail traffic is using many-to-many
NAT, and they don't do DNS for the public side of the NAT [ie, looking up
123.123.123.123 doesn't generate name.blah.tld].
Is there a way to exclude this particular domain from DNS lookups by IP address?
Exim gets the proper public IP addresses from this domain, it just can't look them
up to verify.
Sorry if this has been asked and answered previously, I couldn't find anything in the
FAQ.
