This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its

recipients. This is a permanent error. The following address(es) failed:

SMTP error from remote mail server after end of data:

host []: 554 5.7.9 Message not accepted for policy reasons. See [url=“”][/url]

Have you tried from a different email account? Does only happen when sending to Yahoo?

Its telling you that your email domain has not been authenticated.

Check hat when sending email from CART it meets their criteria

“From” address should map to the same signing domain[list]

[*]Mail from a domain should match the domain in the “From” header


Its only happen from cs-cart, when I used yahoo -mail from cs-cart.

Can this be cause from my hosting company?

They should be able to get it corrected

Thank you, I'll let them know.
