    Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.

    I understand that you would like to establish a connection between Azure App Service and OnPrem SMTP Server.

    You can consider using Azure App Service VNet Integration and integrate the AppService in the VNet where the ExpressRoute Gateway is deployed.
