Certbot is part of EFF’s effort to encrypt the entire Internet. Secure communication over the Web relies on HTTPS, which requires the use of a digital certificate that lets browsers verify the identity of web servers (e.g., is that really google.com?). Web servers obtain their certificates from trusted third parties called certificate authorities (CAs). Certbot is an easy-to-use client that fetches a certificate from Let’s Encrypt—an open certificate authority launched by the EFF, Mozilla, and others—and deploys it to a web server.

If you want to avoid the risk of compromising your server because of accounts who are sending messages indiscriminately to the world, due to the fact that their password was violated in some way, then you can take advantage of Luca Franceschini's rcptcheck-overlimit.sh script, which has to be used in conjunction with the rcptcheck patch (a patch derived by Luca himself from an original work of Jay Soffian).
Since in 2016 Luca has decided to merge his combo with my big patch, he is giving his personal contribution to it. He fixed many bugs and added new important patches and functionalities, often writing himself the code. The script shared here is just the last one and it's quite surprising (at least for me) to observe how many things are performed putting together just 20 lines.
