In this talk we will start by explaining which standards are available to increase e-mail security. We will briefly discuss protocols such STARTTLS, SPF, DKIM, DMARC, DANE and MTA-STS. We also discuss advanced SPF options. Finally, we will link all of those protocols to detect if our domains are being abused for phishing attacks.
