email forwarding rejected: 550 message rejected ... AUP#CXSNDR
550 <email@example.com> message rejected. Refer to Error Codes section at https://www.cox.com/residential/support/email-error-codes.html for more information. AUP#CXSNDR
On several emails I have tried to forward I have gotten the above reject message (Outlook 365, Windows 95). Similar reject from iPad.
On one of the emails I found a link in the body of the email referring to http://click1.info2.xxxx ... for more information. I am guessing that Cox thinks that "click1" link is spam because when I manually removed it, the email forwarded without any errors.
Did something change with Cox spam filtering? Is there a solution to this?
