Okay, let me try to describe what I want to do. The
server should host the mailservice for multiple VPNs.
Each of these VPNs accesses the server through a proxy
with a dedicated IP address. Up to now everything is
fine. Now, I want to add a virus wall or other
security services for some of the VPNs. This would
mean that I want the server only accept those domains
for local delivery that belong to the IP address (i.e.
to the VPN) they came in from. Mail to other domains,
even if they are hosted on the same server, should be
relayed to an public mailserver and would then be
treated as any other incoming mail from the internet.
a small picture to make things clearer
FW A - VPN A - PX A
/ \
the - FW B - VPN B - PX B - qmail
internet \ / server
^ FW C - VPN C - PX C |
| |
|-------non-local mail relay---------|
legend:
- VPN x are different virtual private networks
- FW x are VPN specific firewalls
- PX x are VPN specific mail proxies
The goal is to
- use a common qmail server
- not need to have multiple firewalls for each VPN
Hope that helps,
Peter
