When someone is an authorized user of email, ie, they login to your SMTP server via a good username+password, then you should configure your spam filtering to treat them as trusted. For example, in postfix you could have: smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, [ ...before checks like... ] check_policy_service inet:127.0.0.1:12525, check_policy_service inet:127.0.0.1:10023, Regards, -- -Chuck
