Wordpress by default sends form, contact, and other emails using the PHP mail() function. This function is disabled by default on our servers.
On VPS servers, we can activate it, but it is advisable to leave it disabled to avoid spam from the website itself.
One option is to configure a plugin called Easy WP SMTP in our Wordpress, which allows us to send email using SMTP, that is, through an authenticated email account on our server or an external one. We will explain how to do it.
Installation of the Easy WP SMTP plugin
To install the Easy WP SMTP plugin, we must access the Wordpress administration. Inside, we go to Plugins > Add New.
We perform a search with the words Easy WP SMTP. You will see the following plugin that you must install. Click on Install Now.
Then click on Activate to enable the plugin.
We will now have the Easy WP SMTP plugin installed. Now we have to configure it for SMTP delivery.
Configuration of Easy WP SMTP
To configure the plugin, we must access Settings > Easy WP SMTP. Inside, we will see a screen that indicates the fields to fill in. The configuration we must use is as follows:
Sender's email: email that will send the email.
Sender's name: name that you want to appear in the email.
Reply-to email address: email that will appear when you reply.
SMTP server: localhost
Encryption type: None
SMTP port: 587
SMTP authentication: Yes
SMTP username: email that will send the message
SMTP password: email password
NOTE: These details are for sending with accounts from our servers. If you have an external email service, you must indicate the SMTP details provided by the email provider.
Click on Save Changes to save the settings. With this configuration, we would be ready to send email from our Wordpress, from forms, etc. in an authenticated way.
