Sending emails relies mainly on SMTP, the Simple Mail Transfert Protocol. This protocol is actually quite old: the first traces date back from the 70’s, and the first standardisation took place in 1982 (RFC 821). It is primarily a very simple and insecure protocol, although multiple additional protocols have developed to protect emails and avoid SPAM. In this blog post we review these different protection mechanisms.
