Better yet, just block port 25 TO that ip address and spammers will not
even get the chance t send you spam. They just try for the highest mx

Because some of them will try a lower MX then.
Right now, I am experiencing this:
@ MX 1 fake.domain
@ MX 10 real.domain
@ MX 100 mx2.domain
@ MX 1000 fake.domain
fake.domain have no ip address
Watch out for www.rfc-ignorant.org... if 'no ip address', you could
get your domain blacklisted.
You might want to point your bogus MX to a real IP with port 25 closed.
Or if you have a virtual server with extra horsepower, put a selective
firewall in and let your local SMTPs through. Give them a fast lane for
those times when the normally available MXs are a bit over loaded.
