Using Postfix 2.8.4, I have the following options to smtpd: -o content_filter=dspam:unix:/var/dspam/dspam.sock -o smtpd_milters=unix:/var/run/clamav/clamav-milter.sock,unix:/var/run/opendkim/opendkim.sock,unix:/usr/local/var/milter-greylist/milter-greylist.sock
Reading the postfix doc, it says that "Milter applications are applied in the order as specified". Yet, in the maillog I see milter-greylist listing messages before opendkim. I was wanting to use the results of opendkim in milter-greylist. Perhaps that is not really possible? My guess, from my limited milter understanding, is they are executed piecemeal and that order is perhaps not so predictable. Steve
