This is why backup MXes are a bad idea in the current sewer^Hclimate.
Unless your MX has a list of valid client addresses, it will accept mail
for dictionary-attack targets. This is a Bad Thing(tm).

Well, at least you're not trying to bounce it. That would turn you into a
spam reflector - which is a Very Bad Thing(tm).

Yes - ditch your config. Have a single MX that has your valid addresses on
it. This will probably end up being your side of the ADSL link.
