SpamExperts (3 of 10) - Configuring mail destinations for correct mail delivery
The SpamExperts Destination defines the server where scanned email is delivered - it should be set to your home server - you can find this detail in your welcome email.
Whereas the SpamExperts Destination simply defines the place scanned email is sent - which will almost always be your home server.
You may need to update the SpamExperts Destination if you change your DNS A record to point away from Krystal - for example if you are using a CDN like Cloudflare.
cPanel > Email > SpamExperts
On the next screen you will see a list of domains within this cPanel account - click 'Login' to enter the SpamExperts configuration for that domain
Click the Destinations icon
Initially the following screen will likely show no routes. Click the 'Show Results' button
You should now see the destination list - and hopefully it'll show your home server. If it does show your home server then your destination is set correctly.
If this does not show the correct server you can either click '+ Add a destination' to add a new one - entering the Priority as 0, the correct home server name and Port 25; or you can Edit the existing record - click the drop-down icon and select Edit.
If you add a new record first you will then need to Remove any other records - again, by clicking the drop-down next to the old record and clicking Remove.
If you make any alterations to these Destinations you should make sure to Clear the Callout Cache to ensure your changes take effect immediately.
