0anj,

I assume you are using Xeams in Firewall mode and will forward out-bound messages from your actual server to Xeams, which will then send them out. My answer is based on this assumption.

You need to do 3 things before accepting outbound emails from your actual server:

• Add the actual server's IP address among the relay list
• Add the actual server's IP in White Listed IP
• Add the actual server's IP among the "Trusted IP" for "Auto Learn Sender"

Once this is done, outbound emails will never get blocked.
