Hello, 

Is this a full copy of the bounceback? I can get this reported.

I've been having the same issue

host gmail-smtp-in.l.google.com [74.125.136.26]
    SMTP error from remote mail server after end of data:
    550-5.7.26 This mail has been blocked because the sender is unauthenticated.
    550-5.7.26 Gmail requires all senders to authenticate with either SPF or DKIM.
    550-5.7.26
    550-5.7.26  Authentication results:
    550-5.7.26  DKIM = did not pass
    550-5.7.26  SPF [dingo-blue.com] with ip: [66.96.187.3] = did not pass
    550-5.7.26

Hello Kris6588,

 

I have updated the SPF record for your domain and this should resolve the authentication errors you reported.

 

Let us know if you have any further issue.
