I would go back to client and ask them WHY.
Sounds like an uneducated client trying to tell the expert(you) how to solve
a problem.
If they just want incoming email from the outside scanned for spam before
sending to a windows server, then so be it.
If they want to use linux, so be it.
If they want to use vmware (vps?), why not.
But WHY let the spam it the most venerable and ill equipped windows based
server FIRST?
Maybe they are talking about a physical thing.
Vmware hosting two images: one windows, one linux.
Email comes in to the windows box hosting the linux vmware image. It gets
scanned and send to the windows image.
(however, there are a LOT better ways to do this than that) funny thing, the
above is exactly how we have our internal email set up.
(but using Freebsd instead or linux)
Find out from client just exactly WHY he thinks he wants to do this.
Does he only have one public ip? No big deal, nat incoming 25 a standalone
appliance, scan email, send to windows box on port 26 (config windows to
listen to port 26)
Only have 1U space available ?
Is this a political issue? (ie: RFP says that the anti-spam system must run
under windows?)
