i want to do content filter for multiple conditions to incoming mails.
for example, if mail's header contains "abc" AND  if from address contains "xyz@qw.com"  let the mail be discard.

how can i do that as global ?

on next versions iredadmin, will you add feature of content filter ?

You can try Postfix setting 'header_checks':

i examined these sites but as far as i can see, header_check does not supply us to handle two or more conditions on a header file in a time.

It's mentioned in Postfix document:
http://www.postfix.org/header_checks.5.html

Note:  message  headers are examined one logical header at a time, even
       when a message header spans multiple lines. Body lines are always exam-
       ined one line at a time.
