We check for an MX record associated with the domain, and leave it at that. I'd rather deal with spam than lose a customer.

  a domain without MX records is valid. if a domain/host doesn't have an MX record, MTAs are supposed to try delivering to the domain/host itself.

    Thanks for the tip, I didn't know that. We should change to checking for valid DNS entries then.
