Are you denying incoming or outgoing SMTP traffic?

If you want 123.123.123.123 to stop connecting to your SMTP server,
you would need to create an incoming deny rule with the source address
of 123.123.123.123 and destination address of your server.

P.S. POP3 is a mail retrieval protocol, you cannot send email with POP3.
