Thanks. Fortunately, the Exchange Server is behind a firewall with most of
the inbound TCP/IP ports blocked....so I think our only vulnerability would
be from within. Being a small organization, I'm not too terribly concerned
about that.

If that exchange server has no inbound firewall rules blocking it then
your probably already being spammed. Exchange 5.0 has no
"authentication" functions relating to outbound mail. Thus, anybody
that can see its IP address on the internet can use it to send mail to
anybody and make it appear that it came from a totally different source.
Having no DNS pointers to it doesn't matter because it can be targetted
directly via IP.
The only fix for this is to try and go around the problem with a
duck-tape repair approach or get rid of problem and thus remove exchange
5. Exchange 5.5 and 2000 do not have this flaw.

Hello,
I recently inherited a small site with a single Exchange Server.
The site is a small business and they had purchased Microsoft Exchange
Server 5.0 way back in 1997 but never installed it. Last year, they
hired a consultant to come in and upgrade the hardware on their single
Windows NT 4.0 Server as well as install Exchange. For incoming Internet
email, they're using a single POP3 account with a catch-all domain
forwarding service to forward all emails for their domain to this POP3
account. On the server, they have an application running called POPCon,
which retrieves all the email from this POP3 account, parses the headers
looking for the intended recipient, and then hands off the email to the
correct Exchange recipient via SMTP. For outgoing email, they're using
the Exchange Server native SMTP services to relay all email to their
ISP's SMTP servers for delivery. This is all being done over an ADSL
line with a Hawking Router.
What I'm looking for from any of you is the following:
1. Exchange Server 5.0, it's old and antiquated. However, the IT
budget is
virtually non-existent, so upgrades at this time isn't an option. Any
suggestions on what I should do to ensure the stability and performance
of my Exchange 5.0 Server? It seems MS stopped at Service Pack 2 for
Exchange Server 5.
2. Is it possible to add a disclaimer to all outgoing email
messages in
Exchange Server 5 as I've seen posts illustrate for Exchange Server 5.5?
Thanks in advance.
Regards,
Chris
