How will MTA-STS and DANE evolve?
MTA-STS and DANE will likely see increased adoption as encryption becomes standard expectation. These protocols prevent downgrade attacks that force unencrypted transmission, ensuring end to end encryption protection.
Major providers already support these protocols. As adoption reaches critical mass, they may become expected rather than optional. Senders without encryption enforcement may face scrutiny or filtering disadvantage.
Evolution may include simplified implementation, better tooling, and integration with other security standards. The goal of ubiquitous encrypted email transmission drives continued development.
