I'm not sure I understand exactly what the problem is, but if people are
sending mail through your server to domains which are NOT listed in
esmtpacceptmailfor, (so you are acting as a relay) then they might be
listed in the smtpaccess or they are authenticating with a valid
username and password before they send the mail.
If this guy is coming from an ip address which is listed in smtpaccess
then remove that ip and rerun 'makesmtpaccess'. If he's authenticating
as a user on your system, then either delete his account or change the
password on it so he can't authenticate any more.
I'm assuming here that you have NOT set up courier as an open relay so
that anyone can send mail through your system; it's just this one person
who is using you as a rely. If you have set up an open relay, then you
should undo that! :-)
