Hey there,

Running a mail server on your own is not always an easy process. We have an article/tutorial on this here:

If you’ve read that and still want to run a mail server on your own, I would suggest checking out Mailinabox. We have a great tutorial on setting it up here:

When setting up a web site or application under your own domain, it is likely that you will also want a mail server to handle the domain's incoming and outgoing email. While it is possible to run your own mail server, it is often not the best option for a variety of reasons. This guide will cover many of the reasons that you may not want to run your own mail server, and offer a few alternatives.

Hello all,

What I could suggest here is using an SMTP plugin for your WordPress site.

That way you will be able to specify an SMTP server with authentication which your emails would be going through. You could for example use SendGrid’s SMTP service. This would drastically increase the delivery rate of your emails as well compared to using plain PHP mail.

I’ve been using this plugin for a while now and it works very well: Easy WP SMTP.

Hope that this helps!
