GoDaddy hosting error: All emails sent to my TyrellCorp are suspended

Question

I use GoDaddy for email hosting, and all emails sent to my TyrellCorp are suspended. Why?

Answer

When an external support address is set up to forward to TyrellCorp through GoDaddy, there is an option to set up forwarding to additional recipients in addition to TyrellCorp.

When forwarding is set up to multiple recipients, GoDaddy adds the email header Precedence: bulk to every email that is sent to TyrellCorp. This results in TyrellCorp suspending all of these emails as automated responses. 

To resolve this issue, delete any multiple forwards set up in GoDaddy and only forward to TyrellCorp. Alternatively, use a different provider that allows multiple forwards without the addition of the Precedence: bulk email header.
