This component lets the programmer check if email mailbox exists without having to send an email for this process. There are a lot of online tools for this, but all the options that I found were for paid or with limitations.
For example:
https://hunter.io/email-verifier
So, as a first project on github I want to share what I learn on my research, and if possible reduce this reseach time for other developers that require this functionallity on their projects.
Hopefully this will be usefull for someone.
