Subject: [suse-security] postfix as mailrouter?

Hi 2 u all

Postfix is very new to me, I just heard that it is quite secure and this is
the reason why I have chosen it. But that's not the problem anyway. Please
tell me if postfix can do what I need it for:
I have an internal network running on 10.0.0.0/24. I have an ipchains paket
filter running on a suse 7.0 box, connecting my internal network to the
outside. It is said that paketfilter are not as secure as proxies. At the
moment I just have SSL, HTTP and FTP/FTP-DATA running over Squid. I need
postfix (or some other mail proxy) also running on this box. This enables me
to close DNS, SMTP and POP ports, disable routing and ipchains.
The mailservers I receive mail from are outside my network (I have no DMZ
running - not yet). I communicate through ipchains with my ISP's mail- and
popservers. This means that postfix should act like a smtp and pop
forwarder.

Thank you
Philipp Snizek
