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 Maddy?

maddy's latest release is a security fix, five months after its last feature work.

maddy is an all-in-one Go mail server for SMTP and IMAP. Its most recent release, 0.9.6 in October, requires explicit trust for PROXY protocol headers and closes an auth misconfiguration that could skip password checks. Before that, the 0.9 line ran from March to May: no-downtime config reload in 0.9.0, an LDAP injection fix, and removal of long-deprecated commands.

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.

0.0

maddy's latest release is a security fix, five months after its last feature work.

◆ Current state

maddy is an all-in-one Go mail server for SMTP and IMAP. Its most recent release, 0.9.6 in October, requires explicit trust for PROXY protocol headers and closes an auth misconfiguration that could skip password checks. Before that, the 0.9 line ran from March to May: no-downtime config reload in 0.9.0, an LDAP injection fix, and removal of long-deprecated commands.

◆ Where it's heading

The project is moving from convenient defaults to safer ones, accepting breaking changes on the way. Older conveniences such as SASL LOGIN, STARTTLS plaintext fallback and the maddyctl symlink have been removed, and 0.9.1 flagged several DNS providers for removal in 0.10.0. Two of the last four releases were security fixes.

◆ Prediction

0.10.0 is scoped by the deprecations announced in 0.9.1: expect the flagged DNS providers to go and gandi to require Bearer tokens. The five-month gap gives no date for it.
