SMTP Gateways
Question asked by David Finley - 4/30/2020 at 1:19 AM

I am a little confused by the Gateway configuration options.

I get the Gateway concept just fine, but from what I see...
1. If I have no gateways.. then the server just sends through it's self.
2. If I add a gateway. That becomes active, and all messages go through that.
3. If I add two and set them to round robin then they would share the load.

So questions.
1. What is default gateway in the Domain settings. I can either set a single gateway, or default... does default mean use all, as opposed to use one?
2. If I want to share the load for outbound between the Smartermail Server and say another gateway server. How would I do that?
3. Can I force certain destination domains (say hotmail) to always route via a certain gateway?  Like you can do with an exchange server?

Any tips would be handy on this one.

1. What is default gateway in the Domain settings. I can either set a single gateway, or default... does default mean use all, as opposed to use one?
In the domain gateway settings, "Default" will use any gateways that are configured for round robin. If there are no gateways are configured for round robin, gateways will not be used.

In the beta, we have replaced the "Default" gateway setting with "Round robin" and "None". "Round robin" works the same as the current "Default" option, and "None" will always send messages without using a gateway.

2. If I want to share the load for outbound between the Smartermail Server and say another gateway server. How would I do that?
The only method that permits this approach requires using multiple domains. If you have two domains in SmarterMail, set one domain to "Default" (or "None" for the beta) gateway, and set the other to use a specific gateway. With Build 7242 and earlier, this will only work if there are no gateways configured for round robin.

3. Can I force certain destination domains (say hotmail) to always route via a certain gateway? Like you can do with an exchange server?
In SmarterMail, gateways are  configured based on the sending domain. SmarterMail does not allow specifying a gateway based on the destination domain.

Thanks for the reply. 
As a suggestion, you should allow the ability to configure a gateway for the existing server. ie.. set up localhost or similar as a gateway and allow it to perform a load share in the round robin process.
