DKIM selector record for DNS:

     MDaemon._domainkey.viyouen.com. IN TXT "v=DKIM1; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQChOFLn5f1G+0wcZkhQccKYtd6l/MQXG/nNATqzEo9onVfPWqGQjNb6351IVm1dM+2x4QyzuWn0dheUAJacUlY8sXtK+9l+QaZLPKPQIR9JDfP2PE2uhl7iG5ApaaxNgwNUiJZavKbUGZK4xvQnxbFL2r8l9FHh9Wqhtqj9OzpYbQIDAQAB"

DKIM adsp record for DNS:

     If all outbound mail for viyouen.com is signed:

     _adsp._domainkey.viyouen.com. IN TXT "dkim=all"

     If all outbound mail for viyouen.com is signed and unsigned
     mail should be discarded:

     _adsp._domainkey.viyouen.com. IN TXT "dkim=discardable"

     If some outbound mail for viyouen.com might not be signed:

     _adsp._domainkey.viyouen.com. IN TXT "dkim=unknown"

Important note: the above examples are using your primary domain of "viyouen.com".
You may need to setup similar records using different domain names if you want
to sign mail for any other domains you are hosting.

See RFC 4871 and the most recent IETF draft for ADSP for additional
parameters you can add to your selector and ADSP data in DNS.
