[exim] Abuse Bypassing SA when in To or CC

Hi,

Spammers bypass the SA check when they put abuse@??? in To or CC
field. And putting genuine mail IDs in Other headers.
Here is the ACL i have in exim

check_recipient:

  warn     message       = X-SA-Do-Not-Rej: Yes
           local_parts   = postmaster:abuse

 warn     message       = X-SA-Do-Not-Run: Yes
        local_parts   = abuse:MAILER-DAEMON

This ACL prevents SA to run & reject if it has abuse in its header.

How can i modify this acl to run SA in case it has more recepient other than
abuse, postmaster or MAILER-DAEMON.
