I keep getting a bunch of SMTP Protocol errors just wondering how to get rid of them
there they are
This is an SMTP protocol error log for virtual server ID 1, connection #285. The remote host "xx.xx.xx.xx", responded to the SMTP command "rcpt" with "550 5.1.1 <joe@abc.com>... User unknown  ". The full command sent was "RCPT TO:<joe@abc.com>  ".  This will probably cause the connection to fail

This is an SMTP protocol warning log for virtual server ID 1, connection #292. The remote host "202.93.77.230", responded to the SMTP command "rcpt" with "421 VS14-RT5 Mailbox bounce arrival rate exceeds system limit (#4.2.2)  ". The full command sent was "RCPT TO:<todomewo_aide@yahoo.co.jp>  ".  This may cause the connection to fail.

The first message means what it says - the user is known at the server.
What it doesn't mean is that the server is delivering the messages to the correct server. Therefore after verifying that the address is correct, you then need to look at whether your server is delivering to the correct server by comparing the results of an MX record lookup form your server with the results from a public source such as dnsstuff.com

The second message would appear to be an error with the remote side.
