    Email Not Sent Out

    Addy Sharma

      Hi All,

      An email was set to be sent out to one of our customers but the marketo flow did not trigger the email, when i checked the info tab of the user in the database I saw this strange thing, 550 5.1.1  Recipient address rejected: undeliverable address: host mx2.virtmx-0006[137.166.68.1] said: 550 5.1.1 <... User unknown (in reply to RCPT TO command)

      Does anyone know what is this for?
