Secure SMTP (SMTPs) allows you to send safely emails even on non-secure networks. This is very important in order to protect your privacy and account security.

Thunderbird offers excellent SMTPs support and the following article describes how to enable it.

First we assume you have configured your email following the instructions on how to set up Thunderbird.

Even if you are using a different webhost the instructions are similar.

The most important thing is to find out which IMAPs server to use. If you are a SiteGround client, go to yourdomain.com/cpanel.

You will be redirected to something like https://secureXXX.sgcpanel.com:2083. This means that your SMTPs server is secureXXX.sgcpanel.com.

It is essential to use exactly this server name because our SSL is issued for *.sgcpanel.com. If you connect by SMTPs with any other server name, there will be an SSL warning that the certificate does not match the host. This warning is not fatal but it will pop up you every time you open your email client.

Once you have found out your SMTPs server name, open Thunderbird and go to Edit > Account Settings. There click on Outgoing Server (SMTP) at the bottom of the list. You will see an email associated with the SMTP server in question. Edit it following these steps:

1. Make sure the Server Name is set to your SMTPs server.

2. Under Security Settings, check SSL for Use Secure Connection.

3. To apply the changes click 'OK' at the bottom.

From this point on you will be sending your emails securely using SMTPs.
