title: Underscore in CNAME required by SES not allowed by registrar
body: <p>Amazon's SES mail service requires DKIM authentication.  One step of authentication is to add a CNAME record to your domain's DNS.    </p>
  
  <p>Unfortunately the CNAME record has an underscore.  My registrar, Network Solutions, does not allow underscores in CNAME records.</p>
  
  <p>Is there a workaround for this?  Transferring to a different registrar is an option, but obviously a horrible option.</p>
