SMTP Server
The SMTP Server can be installed to receive mail from sources outside of WinGate for delivery by the SMTP Delivery service.
In previous versions of WinGate the SMTP Server provided the actual delivery services for WinGate Mail. Delivery is now handled by the SMTP Delivery service.
The SMTP Server is only required to receive mail for delivery from users and external sources, who use WinGate Mail as their SMTP server. It can be disabled or removed if needed.
Note
In WinGate some components have the ability to send mail using the SMTP Delivery service. The SMTP Server is not required to provide this functionality.

Bindings
|
The server will automatically bind to any network interfaces that have their usage marked as Internal by WinGate.
If the WinGate mail server is to support sending mail on behalf of remote clients on the Internet, then the SMTP Server needs to be bound to a network interface marked as External (Internet connection) by WinGate.

Remote SMTP servers
If WinGate clients want to send mail through a remote SMTP server, then clients can use any of the WinGate client connection methods such as NAT or WGIC to gain appropriate access to the Internet. In these instances the SMTP Server is not required.
SMTP Server features
Plugins
The SMTP Server is equipped with filtering capabilities which allow you to install the optional data scanning plugins that are available, such as Kaspersky AntiVirus for WinGate. This is useful when you wish to have all client mail that is to be sent by the WinGate Mail, scanned for viruses or malware before delivery.
When used in conjunction with the Intercepting proxy, the SMTP Server can be made to intercept all WinGate client traffic on port 25 (even clients making SMTP requests to remote SMTP servers) and have all of this intercepted traffic scanned before it leaves the network.
SSL connections
Within the WinGate Mail settings, you are able to specify whether the network interface that the SMTP listens for requests on should use SSL. This provides secure communication between the client making the request and the SMTP Server in WinGate. As such, you will need to configure the Bindings for the SMTP server to use SSL.
