Error 550 relay access denied

I get Error 550 Relay Access Denied when the Securline VPN is on.

How can i set the VPN not to redirect my smtp traffice through the VPN

That’s an error related to Email transfer and I’m not aware of any settings in Secureline that can resolve that issue.
Trying googling “Error 550 Relay access denied” and see if the setting in your email client are appropriate.
