It would mitigate against some attacks, and we use this kind of setup at
work, together with mod_proxy, to isolate an IIS server from random IIS
What it won't protect you from (and this is very relevant to a webmail
system) is cross site scripting attacks, where improper parsing of an
email could lead to a malicious email containing embedded
Admittedly, this is a problem common to all webapps, and it requires
quite a rigorous work ethic when programming to avoid creating loopholes
(it's one of those nasties where the bug might be there, but is hardly
noticeable in normal use).
