- 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
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.
