Re: Odd DNS problem, no record for domain.com, but has MX records

I will take the vast majority of my moments of brilliance to the
grave, but all my moments of stupidity should be well documented:

I set 'disable_dns_lookups' to YES, stupidly thinking it would merely
disable doing reverse lookups against connecting hosts; unnecessary
overhead in my closed network.

This also meant that is would not do MX lookups, just try to deliver
mail to the A record of the root domain name; if it has one.

Removing that line from the config, an reverting to the default NO, fixed it.
