Hi all. Parts of this have been discussed elsewhere, but I haven't
seen anybody describing quite this setup. I'm reconfiguring a network
to have a dedicated firewall machine, on which I want to run qmail.
But, I don't want the firewall machine reaching in to the rest of the
network to do delivery; I want it to turn around and forward any
incoming mail to the "real" mail server on the internal network. I'd
also like the reverse path for outgoing mail; the internal mail server
forwards to the one on the firewall, which takes care of getting it
out into the rest of the net.
---+ +----------+ +-----------+
| | Firewall | | Internal |
Net|----->| |-------->| Server |
| | Qmail | | Qmail |
|<-----| |<--------| |
---+ +----------+ +-----------+
If anyone can shed light on how to set this up, or point me at some
docs, it would be greatly appreciated.
Thanks in advance.
