Modern Email
summary
Argues that running mail is practical today using modern stacks: JMAP replaces IMAP/SMTP with HTTP for JMAP fast mobile-friendly sync and single auth; delivery still requires DKIM/SPF/DMARC and DNS reputation. Names tools that work in production: Exim/Postfix MTAs, Dovecot, SpamAssassin vs Rspamd (Rspamd catches more spam), Stalwart aiming at webscale, object storage via an S3 AGPL garage plus WireGuard for encrypted blobs, and Sequoia PGP for safer keys. Cites Google serving 1.8 billion mail users as the scale to match.
