Episode description

How do you secure your email transport? Richard talks to Gareth Gudger about the various additional protocols and approaches essential to transporting email. Gareth reminds us that SMTP, like the Internet, was not designed with security in mind, so we have to add layers to try and improve things. It is an acronym soup of SPF, DKIM, DMARC, MTA-STS, and DANE - but every acronym gets a definition! Sure, there is more to email security than just transport, but arguably, this is the place to start. And after that - focus on identity security!
