I am guessing when this happens: postfix/smtpd[879005]: connect from smtpout79.briteverify.com[54.175.215.209] postfix/smtpd[879005]: 4J0QTC1PzHz4l3gS: client=smtpout79.briteverify.com[54.175.215.209] postfix/smtpd[879005]: disconnect from smtpout79.briteverify.com[54.175.215.209] helo=1 mail=1 rcpt=1 quit=1 commands=4
They are probing for valid usernames. Is there a way to have it output in the logs what RCPT address they supplied?
