laravel 5: sending email does not work - php

Question

I'm new to laravel and am currently stuck when trying to send an email like this:
Mail::send('emails.pwreset', $mydata, function ($message) use ($mydata) {
$message->from('foo#bar.de', 'Password reset');
how can I enable/configure the mailing function?
here's my laravel error message:

Answer 1

It looks like /usr/sbin/sendmail does not exist. Is sendmail installed and properly configured?
Also check the Swift Mailer settings inside your application.
