As specified on the http://www.postfix.org/FILTER_README.html page.
So, here is my current setup from master.cf: smtp inet n - n - - smtpd -o content_filter=dspam:unix:/var/dspam/dspam.sock dspam unix - - n - - lmtp -o smtp_send_xforward_command=yes -o disable_mime_output_conversion=yes -o smtp_generic_maps= -o disable_dns_lookups=yes localhost:10026 inet n - n - - smtpd -o content_filter= -o receive_override_options=no_unknown_recipient_checks,no_header_body_checks,no_milters -o smtpd_helo_restrictions= -o smtpd_client_restrictions= -o smtpd_sender_restrictions= -o smtpd_recipient_restrictions=permit_mynetworks,reject -o mynetworks=127.0.0.0/8 -o smtpd_authorized_xforward_hosts=127.0.0.0/8 Of course, dspam doesn't handle xforward so that's actually irrelevant I think. This example doesn't exactly match either the simple, or the advanced. I actually don't understand what it is, but, am wanting to make this work well via the advanced method IF the doc is current about performance gains and less bounce probability. So, does this qualify as the advanced method? That method says you can have your own filter listening on port 10025, but, doesn't give an example of that, and, also, doesn't really specify if a socket is ok instead of a port. The simple method seems to use a pipe. I am not using a pipe. The advanced method uses a spawn from smtp, I avoid the spawn. So, confused! What I am wanting to get out of this is the fastest possible configuration that allows me to use dpsam. Steve
