I've had catch-all email forwarding setup and working for years. But now any email sent to my domain bounces with this error:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain fentonvt.info by fentonvt.info. [143.95.77.232].
The error that the other server returned was:
550-Please turn on SMTP Authentication in your mail client.
550-mail-pf0-f175.google.com [209.85.192.175]:32882 is not permitted to relay
550 through this server without authentication.
Can you please help?
