Tutorial TLS Email spoofing

n4zgu1 · 01-22-2023, 04:11 AM

Send emails from almost EVERY email address. The addresses which are connected in any ways with united-internet, a big tech company, will pass the spam-protection. Providers like GMX, Web.de, ionos and many more are subsidiaries of United-Internet. The emails will be TLS encrypted. You CANT see if the email was spoofed or is real.
Just enter the email address you want to send from, the receivers address, the name that should be displayed, subject and message and there you go.
You all know, for educational purpose only Wink
