Hmmm...

We've run into a similar problem: SBS 4.5 (= MS Exch 5.5 + MS Proxy 2.0
on the same machine), trying to collect inbound mail using SMTP. We've
added all the filter variations mentioned in this thread (including the
recommendations in Networkgods FAQ), but no joy unless we allow the
remote SMTP server to access all ports (port 25 alone doesn't work).
I'm worried about applying this "fix" long-term, in case someone spoofs
the Demon punt's IP address to get into our server... Is this
technically possible, or am I just paranoid (and ignorant ;-) )? Any
other suggestions?

Apologies in advance for the stupid questions. I'm new to NT admin, so
it's baptism by fire at this end!
