Securing email transport: TLS, DANE & MTA-STS¶

Email might feel like digital magic, but without proper encryption, it’s more like a postcard—readable by anyone who intercepts it. Transport Layer Security (TLS) fixes this by scrambling messages in transit, but there’s a catch: not all TLS is created equal.

Without these protections, your emails are at risk of:

• Eavesdropping (via unencrypted connections)

• Spoofing (fake servers pretending to be yours)

• Tampering (modified content in transit)
