@noplasticshower I self-host with Dovecot 2.3 + Postfix on a VPS.
No issues with TLS so far — using Let's Encrypt with SNI for multiple domains.
SPF/DKIM/DMARC all set up with hard fail. Deliverability has been surprisingly good.
Honestly the hardest part was getting the PTR record right with the hosting provider. Once that matched, everything was ok.
What TLS issues are you seeing on 2.4? Curious before I upgrade.

Quick question for the infosec community: what email encryption standard do you recommend in 2026?Quick question for the infosec community: what email encryption standard do you recommend in 2026?
I have been comparing X25519 (Curve25519) vs RSA for key exchange. X25519 is ~500x faster for key generation with 32-byte keys vs 256+ for RSA.
Anyone using ECIES pattern (X25519 + HKDF + AES-256-GCM) in production?

I got tired of Gmail reading everything, so I built a self-hosted
alternative with:
- X25519 + AES-256-GCM encryption
- Postfix/Dovecot on a French VPS
- SPF/DKIM/DMARC + fail2ban
- An AI cockpit that classifies urgent vs noise
Curious what setups other infosec people use. ProtonMail?
Self-hosted? Something else?
