That's not an Evolution error per se. Evolution is reporting what the
SMTP server reports back.  This sort of error is because you are trying
to send email through a server to a different domain and it is not
allowing you to (it only accepts email for domains that are hosted on
the server).

Check that your SMTP server & port in the Evolution configuration is
correct.

SMTP servers should only allow relaying if you are logged in - so make
sure the SMTP authentication is turned on and correctly configured.

If other mail clients are OK, then check the Evolution config against
those.
