Topic: SMTP Server in Server-Only mode

[pietdejong]

Hi I have an SME 7.1 server running in server-only mode behind a PIX firewall and a static IP.
Currently we are using multi-drop.

I would like the SME server to accept outside SMTP connections ( point the MX record to our static IP ), which the firewall can forward to the SME.

Is this possible without setting the server into gateway mode ? ( Since this server allready resides in a DMZ )

I saw this post, but not entirely sure if this applies to my scenario:

I am running SME Server release 7.3


Many thanks

In the firewall, you can do a port forwarding to the IP Address of your SME SERVER (server mode).  In your case, it is in DMZ so point it to that IP.  However, take necessary precautions to prevent being an Open Relay.

Will the SME server accept SMTP connections from the Internet ?
Is the SME Server not an open relay in this case, are there any options I can set ?

If you are referring to other mail servers, then yes.

If you are referring to email clients, then no by default, but you can enable authenticated smtp connections in server manager.

There has been some discussion on the wisdom of running server-only mode in DMZ. I have not seen anything recently but I am not sure that you are firewalled in that configuration.

Maybe somebody that knows a lot more of what actually changes when you do server-only could weigh in on this.
