Thank you for contacting us regarding a "550 Rejecting for Sender Policy Framework" bounceback message. I have seen instances where this is caused by a domain missing SPF or DKIM records, ensure they are set up correctly. Our Bounceback Parser tool may help troubleshoot as well.
If your problems persist we are happy to help but will need some additional information such as the full headers of the returned email message. If you don't want to post it here in the public forums you can submit it privately to our live support team via ticket.
