Top Level Domain (TLD)
A Top Level Domain (TLD) is the last segment of a domain name, representing the highest level in the domain name system. It typically consists of two or more letters and indicates the purpose or geographical location of a website or entity. Examples include .com, .org, and .net. TLDs help categorize and organize websites on the internet, facilitating easy navigation and identification.

What is a good TLD for a mail server domain?
This is dependent on the use case you have. We recommend using customer domains
for single mail systems of a company. If you want to run a general purpose with
hundreds or even thousands of clients, then
.com are a good choice,
as they have a great reputation for mail systems.
If you do stupid things or abuse a domain for spam, your system will get in trouble independent of the domain or TLD your systems are setup on.
