An email privacy test tool.
cool tool alr tried this like 2 years ago, good to check what your email service blocks 🙂
Error: "Can't send mail - all recipients were rejected: 451 Temporary local problem - please try later"
PrivacyTools i think they blocked some email services. When I tried with gmail and protonmail it worked but when I tried with cock.li it gave this error
wont be added for now
