Thanks all for the input especially for Eesger. Yesterday we able block the certain subject to certain recipient using spamassasin by giving high score.
But another question appear, how to allow certain words to certain recipient? Like firewall in freebsd or another OS that can allow certain IP by making the firewall default as block. As far as I know spamassasin will sum all scores, for example : first rule I want to "allow" subject word "test" with score -2 and second rule subject "test2" with score -2 then third rule with subject character "e" as higher score and spamassasin should mark it as spam. If I test email with subject "test" then it will also hit the third rule, I know I should ask in milis spammasasin about this but if anyone know how to do that it will be great .

If your receiving SMTPDs restrictions are sane, a reject from the MDA will not cause backscatter. It will cause the correct DSN to be sent to the correct sender. Anyway, if you must reject it at SMTP time, there is smtp_proxy to put $whatever in between. -- J.
