   I get a ton of spammers trying to dump email to my server via random names against subdomains of a domain. ie bob@subdomain.domain.com
   
   Is there a way at the dns level to kill off any and all subdomain MX traffic?

   Hmm, maybe make bogus MX records for each subdomain, like
   
   subdomain.domain.tld MX 0 imnotamailserver.tld.
   
   If that makes any sense.
