- 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 master.cf. 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.
