Heya. I've had a really simple Postfix server running for a couple of months. I managed to get a decent hang of smtpd_*_restrictions and been rejecting a bunch of spam. Not enough though so I'm looking to do some more protection.
I've been reading about AddOns, and the lots of available ProxyFilters and Milters. I printed out and read the SMTPD_PROXY_README and MILTER_README how-tos. Lots of info, but I got different ones working ones working one at a time on a test box. In the MILTER docsument there's a Limitation setcion that says "When you use the before-queue content filter for incoming SMTP mail (see SMTPD_PROXY_README), Milter applications have access only to the SMTP command information; they have no access to the message header or body, and cannot make modifications to the message or to the envelope. " Does that mean I can't use both? I was going to try something like smtpd inet - - n - - smtpd -o smtpd_proxy_filter=inet:127.0.0.1:12345 -o smtpd_milters=inet:127.0.0.1:54321 .......... Can I do both in the same place like that? And what order to the hand-offs to the proxy and milter happen in? Is it asynchronous, or does is depend on the order they're written in the config file? Sorry if I'm not seeing it right it front of me. -- Bob
