    "Recipient Blackholed"?

    Kim Parrott

      Recently noticed a few people in our database marked as 'Email Invalid' with email invalid cause "551 5.7.0 [internal] recipient blackholed".  Any explanation as to what exactly blackholed means would be really helpful.


      Thank you in advance!
