Hellow.

Is it possible for Laravel 5.5 to configure the sending server for each email separately?

I have several clients who each need to send emails from their server.

This is promising. https://laravel.com/api/5.5/Illuminate/Mail/Mailable.html#method___call

But I can't find how to configure the parameters if it's the right place.
