      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[] said: 550 5.1.1 <... User unknown (in reply to RCPT TO command)

      Does anyone know what is this for?
