The term Fake MX doesn't seem to be used consistently. We are using a
Fake MX, which responds a temporary error to every e-mail. At the high
end there is no problem with this setup but on the low end we
experienced problems with certain mailers. So we listed a so called Null
MX on the low end. This is a connected ip address with the smtp port
closed. This is prefered to a unconnected/unrouted ip address.
To sum it up:
MX 10 nullmx.domain.com.
MX 20 mail.domain.com. <-- the real smtp server
MX 30 fakemx.domain.com.
As a matter of fact there is no smtp log on the Null MX. So it is
sometimes hard to debug e-mail problems.
Best regards
