EFW Support

Hi guys, I am pulling my hair out trying to get efw to spam and virus check incoming emails.

Can anyone give me a few examples of how efw and exchange should be set up?

I currently have..

Internet >> EFW >> Exchange server

I have inherited this network so am just getting to grips with it. The exchange server seems to be set up with an SMTP Virtual server that points to smtp.nildram.co.uk

Exchange is sending and receiving fine but I would like efw to check all incoming emails before they reach the exchange server.

Any help will be much appreciated.

Matt

Matt,

Disable all Spam and Anti-Virus services to get everything rolling

Then:

Go to Proxy>>SMTP>>Domains
     Add your e-mail domain to the "Domain:" field
            [such as ^emailuser@ourdomain.com] add as many ourdomains.com as you have to this list that your internal mail server handles
     Add your internal exchange server IP address

(I chose to add a router behind our current network firewall to test mail relay prior to implementation; this allowed me to roll out the endian appliance in phases, by selectively changing port fwrd rules.)

Test your settings by using telnet [or whatever] to connect to endian firewall ie.

>telnet [external interface endian IP addr] 25
------------
c:ehlo mailservername.domainname.co.uk
s:(endian reply)
c:Mail From:<youre-mail@yourdomain.com>
s:(endian reply)
c:RCPT TO:<youre-mail@yourdomain.com>
s:(endian reply)
c:Data
s:(endian reply)
c:Subject:TESTING
c:TESTING
c:
c:.
c:
S:(endian reply)
c:QUIT
s:(endian quit)
-----------

Then check your inbox and endian logs to see what is happening,

Let me know how you make out, if you're having trouble smtp logs would help.

Thanks for the info.

Do I need to port forward 25 to the exchange box?

Thanks,

Matt

No, The proxy handles the mail relay; so no forward rule need be set on the endian firewall.

Thanks Jerror. I will try it and see how I get on.

Matt

All sorted now. It was the port forwarding og port 25 that was bypassing the spam filter. Thanks for the help. Much appreciated :)
