That makes sense and seems to have done the trick. Thanks!! What I still don't get (and maybe never will), is why...
1) On the Lenny server, the main.cf content_filter sent mail to 10028, the relay port for dkim_proxy_out, and this system worked! I might be able to accept sending to the listening port, but the relay port just doesn't make sense to me. 2) On the current system, the main.cf content_filter configured for 10024 or 10028 seems to be totally inert, not doing anything at all for mail received from the outside. It's only when I loop back to 10024 after the pickup filter that messages are scanned. Theories/explanations are welcome regarding the above. In the meantime, things seem to be working as desired, and that is some consolation. :) Thanks again! -- View this message in context: http://postfix.1071664.n5.nabble.com/postfix-amavis-not-scanning-email-tp89098p89114.html Sent from the Postfix Users mailing list archive at Nabble.com.
