Easy option: Allow AUTH on the submission port only. That way you can specify the content_Filter in master.cf for that particular smtpd, e.g. like this: submission inet n - n - - smtpd -o smtpd_recipient_restrictions=reject_authenticated_sender_login_mismatch,permit_sasl_authenticated,reject -o content_filter=foobar: Hard option: Use a policy daemon to return "FILTER foobar:dummy" if the user has authenticated (sasl_username attribut is non-empty) See http://www.postfix.org/SMTPD_POLICY_README.html for the policy delegation stuff See http://www.postfix.org/access.5.html for the "FILTER:" stuff -- Ralf Hildebrandt Geschäftsbereich IT | Abteilung Netzwerk Charité - Universitätsmedizin Berlin Campus Benjamin Franklin Hindenburgdamm 30 | D-12203 Berlin Tel. +49 30 450 570 155 | Fax: +49 30 450 570 962 ralf.hildebra...@charite.de | http://www.charite.de
