Re: How do folks firewall MS Exchange?

[Chris Cappuccio <chris () empnet com>]

The best way to handle this is probably to use some kind of SMTP proxy server
between the outside and the NT server, with no incoming access of any kind
allowed to the mail server....Oh and for people to connect in for
calendaring, VPN ??? Of course, this assumes you trust anyone who might have
access to a computer which is connected in on the VPN.
