Fighting spam by verifying user emails by inbound message receiving

Alex, a software engineer and solo founder of ProxiedMail, discusses the issue of spammers and email existence checkers on product websites. He explains the importance of maintaining a good email delivery record, especially with Gmail, ProtonMail, and Tutanota. To prevent spammers from using their products, they implemented a new email verification system where customers must send an email to a dedicated address for verification. This method prevents potential attacks and ensures that email verification is not abused. The solution is based on ProxiedMail webhooks, which can be attached to an email address created on ProxiedMail. Users can also use their custom domain for verification. The article provides step-by-step instructions for setting up this system and includes coding details for a Laravel app.
