Hello List, is it possible to have postfix listen on two network interfaces, but the same port and use two different content filter for mails depending on where they come in? I have the following config: - incoming mail via eth0 is spam-checked and forwarded to exchange server - outgoing mail comes from the exchange server and must not be spam-checked when going out. Actually now I have three Ports open for postfix-SMTP (incoming,spamd,outgoing), and three smtp-instances running via config from master.cf. Now we need to close the port for outgoing mail. (And I don't want to do a redirect with iptables!) Thanks a lot! -- Mit freundlichen Grüßen Markus Feilner -- Linux Solutions, Training, Seminare und Workshops - auch Inhouse Feilner IT Linux & GIS Erlangerstr. 2 93059 Regensburg fon: +49 941 70 65 23 - mobil: +49 170 302 709 2 web: http://feilner-it.net mail: mfeilner@feilner-it.net
