There are various things you can do. For domains that don't have MX
records, see mx_domains (but you will fail a lot of mail if you turn it
on globally).

For domains that route to the local host, off the top of my head,

. stick self=fail_hard on the router that detects them

OR

  . stick  self=fail_soft  on the router that detects them and do 
    something with them in the next router (which can test other 
    conditions if you want)


OR

  . write your own condition, using the dnsdb lookup type to look up the 
    MX records
