(FAQ) Can I disable A-Record lookups when MDaemon is processing mail?

Can I disable A-Record lookups when MDaemon is processing mail?

When MDaemon doesn't find a MX record for a domain, it automatically tries to find an A-record so it can attempt delivery there.

There is no way to turn this off - MX records are optional according to RFC so MDaemon will always try the A-record.
