Edit main.cf & tambagkan

smtpd_recipient_restrictions = check_sender_access hash:/etc/postfix/sender_access

restart postfix

You can also use spamassassin to blacklist email address. Just add to your own spamassassin configuration or to /etc/mail/spamassassin/local.cf file:

vi /etc/mail/spamassassin/local.cf

Append blacklist as follows:

blacklist_from user@abadboy.com

Save and close the file. Restart spamassassin:

/etc/init.d/spamassassin restart

spamassassin will marke mail as SPAM instead of rejecting the same.
