What is Dovecot?
Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
What is Superhuman?
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
Dovecot vs Superhuman: editorial side-by-side
Dovecot
2.5COMMS
Dovecot's 2.4 branch is being hardened release by release after a breaking rewrite.
◆ Current state
Dovecot is the IMAP and POP3 server behind a large share of the world's mailboxes. The 2.4 branch opened in January 2025 with a deliberately incompatible release — configuration files must be rewritten, the plugin section is gone, and several long-standing features were removed outright — and every release since has been consolidation on top of it. The pattern is consistent: each point release leads with critical CVE fixes, then lists incremental changes. The latest, 2.4.5, carries twelve CVEs alongside post-quantum ML-KEM support, full-text phrase searching and a throttling response code.
◆ Where it's heading
Two things are being worked at once. Security is the visible half, and the volume is striking — resource-exhaustion and parser issues in IMAP THREAD, LIST and ID, a CRIME-style compression side channel, an authentication bypass through XCLIENT forwarding. The quieter half is that fixes are increasingly gated behind version declarations: the THREAD fix needs a new index format enabled only by raising dovecot_storage_version. That mechanism, introduced with 2.4.0, is now doing real work, letting operators take format changes on their own schedule.
◆ Prediction
Experimental flags for mail UTF-8 and IMAP4rev2 have carried unchanged through every 2.4 release so far; the next branch-defining move is one of those graduating to default rather than another security round.
Superhuman
5.0COMMS
Superhuman is becoming the email layer for AI agents, not just the fastest email client.
◆ Current state
Superhuman has reached cross-platform parity with a complete mobile redesign and expanded its AI footprint substantially. Auto Drafts 2.0 now draws from inbox, calendar, and web context to produce drafts that users send unedited 60% of the time. The MCP integration exposes all connected Gmail and Outlook accounts to Claude, ChatGPT, and other agents simultaneously.
◆ Where it's heading
The product is converging on a model where Superhuman acts as the intelligent intermediary between users and their email — whether the user is driving it directly or delegating to an AI agent. Outlook category support and Gmail label sync for drafts extend this to more of the enterprise email surface. The direction is less about speed and more about AI-augmented inbox ownership.
◆ Prediction
The next move is likely deeper agentic capability: scheduled tasks, autonomous triage, or proactive send — going beyond drafting into taking action without the user in the loop.
