Oggetto: [FW-1] SMTP Security Problem

Hi to all,

I have an Exchange 5.5 Server. Then I setup my SMTP
Resource on our FW-1 to avoid spamming or relaying.
Then I encountered problems like "mailbox unavailable"
-> if i am sending from yahoo to our domain, or
"Relaying is Prohibited" -> if I am sending mails
outside.

this is my setup:

---------         - - -
exchange |       |      |
   5.5   |-----> | FW-1 |-----> Router Gateway
10.4.2.10|        - - -
---------

I used FW-1 to define a Static NAT for my Mail Server
from 10.4.2.10 it becomes a public ip.

This is my rule:

any ---> mail Server  -----> SMPT Resource --> accept
         outside interface
         (public ip)


why is it that I am encountering these problems? How
can I make it run right?

Thank You


Your Help is very much appreciated,
JGuevarra
