    I get a ton of spammers trying to dump email to my server via random names against subdomains of a domain. ie [email protected]

    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.
