Hello,

In addition to what KFSys mentioned already, what I could also suggest is looking into a managed SMTP service like SendGrid. That way you will still be able to send out emails from your server by specifying the SendGrid SMTP server, but you would not have to manage the SMTP service yourself. They also provide a free plan which is sufficient in most cases.

Hope that this helps!

Best,

Bobby

Hi @HappyTech,

So, you’ve said you already have a WordPress website installed and you are using Nginx, that’s cool, good job!

Now, regarding SMTP, I’ll urge you to check the following article:

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-18-04

As a whole, it’s easy to create an SMTP send-only service with Postfix. Having said that, I’ll recommend you to use the third-party mail application for SMTP as well as for receiving mails.

Additionally, third-party mail applications are not hosted on your Droplet. That’s the idea for these mail apps, to not be used on your Droplet so that they are not influenced by your setup.
