Small script to send mails with attachment from folder with Gmail

Uses nothing but python 3 modules.

Create a folder named mail_files and within this folder done and new.
You can place all the attachments within the new folder.
When the script is ready all attachments send will be in the Done folder.
If the script crashes, you can rerun the script as it will start
where it stopped.

You need an gmail app password for this to work
