Example

Given this:

10.100.0.10: Exchange Server (exch1.example.com)

10.100.0.100: SonicWALL Email Security appliance (esa.example.com)

You might have two paths that look like this:

Inbound

Source IP

Listen On

Destination

Any

Any:25

(proxy) exch1.example.com:25

Outbound

10.100.0.10

Any:25

MX

In this scenario, any message that arrives at the SonicWALL Email Security appliance from 10.100.0.10 will be treated as an outbound message, handed off to the MTA component in the system, which will deliver the message via MX-lookup on the domain in the TO field. Messages that arrive at the SonicWALL Email Security appliance from any other IP address will be treated as an Inbound message, and delivered directly to the Exchange server. The SonicWALL Email Security appliance always gives preference to specific matches (for example an exact IP address match takes precedence over “Any”).

Another example using port numbers to distinguish which path a message should take:

Inbound

Source IP

Listen On

Destination

Any

Any:25

(proxy) exch1.example.com:25

Outbound

Any

Any:2525

MX

Another alternative would be to assign your SonicWALL Email Security appliance multiple IP addresses, and have it listen on one for inbound and one for outbound.

In all of the above cases, the admin will configure Exchange to deliver outbound email to the IP address and port number where the SonicWALL Email Security appliance is listening for outbound mail.

To test your SonicWALL Email Security appliance, click the Auditing button at the top of the SonicWALL Email Security appliance user interface and search for your sent email to verify it has been sent and received.
