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.

What is Stoat?

Stoat moves to release candidates and Gerrit, and gives server admins more control.

Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.

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.

5.0

Stoat moves to release candidates and Gerrit, and gives server admins more control.

◆ Current state

Stoat's 0.16.0 release candidates add server controls: invites with expiry and use limits, permission to block external emojis, and bot roles that grant permissions when a bot joins. The team is also piloting Gerrit as its main source control and will now ship release candidates and backports.

◆ Where it's heading

The feature list is about moderation and bot management for server owners, and rc.1 adds OpenTelemetry tracing for the file service. The process change toward RCs and backports suggests the team wants steadier releases for self-hosters.

◆ Prediction

A final 0.16.0 should follow the two RCs; the entries do not say when.
