If you are running a web server or a VPS, you may encounter the need of sending emails using your PHP application. In the same way, if you are running a Wordpress blog or you are using any kind of CMS and you would allow your visitors to send you emails using a Contact form (for example using the Contact Form 7 plugin for Wordpress) you may need to install a simple program into your web server called sendmail.

A couple of weeks ago I moved my Wordpress blogs from a trivial shared hosting to a more sophisticated VPS running CentOS 7 since I was in search of more flexibility from my server. During these days, I learned a lot about managing a web server on my own and I'm still currently learning a ton of interesting things about this topic.
