Email is a crucial component of our online lives. Almost everything we do online requires an email address, including creating login credentials, signing up for newsletters, and leaving website comments. There's a good chance you've already encountered spam if you have an email address.

Introduction

The most effective method to protect a server from sending spam is to prevent it in the first place.

What is Thunderbird?

Thunderbird is one of the most widely used open-source email clients in the world. Mozilla originally developed the software in 2004, but the project waned in 2014/15, and Mozilla stated that they would only deliver security and maintenance updates in the future. Until recently, the community maintained the software when a Mozilla Foundation subsidiary, MZLA Technologies Corporation, took over. Today, the improvements in security and stability are very much appreciated, and since version 78, Thunderbird has built-in OpenPGP encryption technology enabled by default. Earlier versions used the available PGP technology, but it needed to be installed as a supplemental plugin. 

What is the Gmail Blacklist?

As one of the most trusted email providers, Google keeps top-notch security by maintaining their own blacklist and security information. With the numerous users the company provides email accounts to, there is an overwhelming amount of data that Google can scrutinize for spam or malicious emails. By gathering this valuable information, rules are created to filter problem content. These rules are highly sophisticated, and as this data is compiled, specific IP addresses are flagged and sorted into what is called a blacklist.
