未testing; 这应该让你开始：
:0 * ^Subject:.*AAA.* # subject condition * !^X-Loop: [email protected] # prevent mail loops { :0 c B # c: make sure you still receive the mail, B: check body instead of header * BBB # body conditions * !CCC * !DDD | (formail -r -A"X-Loop: [email protected]" ; echo "This is my reply") | $SENDMAIL -t }
