Request for opinions of webmail appliances

["Douglas Schlachta" <DouglasSchlachta () cplodges com>]

I would like to put this out as a question for anyone involved in a
project for web mail server systems.

I am looking at instituting a web mail server system from a DMZ that
would also interact at a secure level with an Exchange server on the
internal network.

Can anyone give me there comments on any systems that they are or have
used in this scenario or something similar?
