Re: Scared as hell with SBS 2003 Exchange

And who is that "expert" advising you to put Exchange in a DMZ and what
security risks are they saying you have with an SBS Exchange box? I'd calm
down and ignore them unless you want to give up totally on SBS and have
separate boxes for Exchange etc. at the much higher cost that will entail.

Someone informed me today that my SBS Exchange server is out there in the
open for all to access. Please help calm me down and clarify my
configuration:
I have a Cisco Pix 501 firewall opening ports 25, 443, and 4125 from it's
public outside IP address and forwarding them to the outside interface of
a
Symantec Gateway Security 360 appliance, forwarding those same ports to
SBS
2003's internal IP address.
This same person told me I need to put the Exchange server on the PIX 501
DMZ interface and use a different public IP address just for Exchange.
I'm having problems currently with my new SBS 2003 Exchange configuration
which is using DNS to route all mail. I've heard that I need to set up
reverse DNS for my public IP address to allow messages being sent to
certain
domains such as verizon.net, nyc.rr.com, optonline.net, etc. I'm getting
messages as follows:
=================================================
#5.7.1 smtp;550 5.7.1 <user1@xxxxxxxxx>... Relaying denied>
Could not deliver the message in the time limit specified. Please retry
or
contact your administrator.#4.4.7
=================================================
Post on this user group have told me to use a smart host method for
sending
mail.
Where do I go from here? What should I do?
All help is appreciated. Thank you.
Sincerely,
Joseph M. Fulgieri
