SwiftMailer, PhpMailer, etc: Difference between mail() and sendmail
<p>I often read that PHP's <strong>mail()</strong>-Function uses <strong>sendmail</strong> internally.</p>

<p>So why do Mail-Libraries like SwiftMailer, PhpMailer, etc give us the chance to CHOOSE between <strong>mail()</strong> and <strong>sendmail</strong>?</p>

<p>Isn't it the same thing?</p>

<p>Never heard anyone saying that it's NOT the same thing!</p>

<p>Please help, 'cause I'm really confused about that!</p>
