This typically happens when you try to send an email from your site, like a reset password link or a notification.

Often, it’s tied to your web hosting provider, which might have certain restrictions on the mail system.

Here’s a simple guide on how to quickly resolve this issue using two methods:

Method 1: Contact Your Web Hosting Provider

As the error suggests, your web host might have certain restrictions.

The first and most straightforward solution is to:

Reach Out: Contact your web hosting provider’s support team and explain your problem.

Discuss: They’ll either guide how to enable the function or inform you about specific restrictions they have in place.

Method 2: Setup SMTP with a Third-Party Email Service

If, for some reason, you can’t contact your hosting provider or they don’t include email services in your plan, you might need to consider using an external email service provider.

Here’s a simple way to set up SMTP on WordPress:

Go to your WordPress dashboard and install the “Post SMTP” plugin. I previously recommended “Fluent SMTP,” but “Post SMTP” is my preferred choice because of its lightweight.

After setting up the Post SMTP plugin, integrate it with Brevo (formerly Sendinblue).

Brevo is an excellent choice for email and marketing platforms. Follow this setup instruction and ensure everything is integrated properly.
