Problem with email account, rejected by recipient domain
Hi,
There seems to be a problem with my email step (I've changed MX records to reroute to gmail). Bounce report as follows:
Delivery to the following recipient failed permanently:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain c********s.co.uk [198.46.81.210].
The error that the other server returned was:
550-Please turn on SMTP Authentication in your mail client, or login to the
550-IMAP/POP3 server before sending your message. mail-vk0-f52.google.com
550-[209.85.213.52]:33635 is not permitted to relay through this server without
550 authentication.
Any help would be appreciated.
Cheers,
Chris.
