Email signing in Laravel 5.1

I apologise in advance if this is an amateurish question. I am trying to setup my app in laravel 5.1 so when a user signs up they can send emails from their domain via mycompanydomain.com.

They currently have to add their own SMTP details to send outbound emails from their accounts but its putting strain on our support.

Is there an easy enough way to achieve this OR anything I can use from Git?
