postfix - one interface, two different content filter?
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!)

This is only possible if you use two different ip adresses for each interface, bind one smtpd on each for port 25 and select the filter depending on this via master.cf c'ya sven -- The Internet treats censorship as a routing problem, and routes around it.

right - i was able to solve this, thanks to andreas winkelmann, this box is a router, so this ist no problem. thank you! Am Freitag, 28. November 2003 12:49 schrieb Andreas Winkelmann: (...)
Das sind dann trotzdem mehrere Instanzen, aber sowas müsste in der master.cf doch trennbar sein.
192.168.10.1:25 inet .... smtpd -o ... 192.168.11.1:25 inet .... smtpd -o ...
