    - you should not use REJECT in amavisd-new. either PASS or DISCARD.
    otherwise, you will backscatter innocent people when sender is forged.

    - you can whitelist system mail either by setting
        -o content_filter=
    under "pickup" in This means that mean submitted via the
    sendmail command will not be filtered. whether this is appropriate
    depends on your setup (if you have a php mailer on the system, you may
    not want disabling the filter).

    - or you can whitelist these in amavisd-new itself. read amavisd-new
    docs or ask on its ML.
