Stoat vs Rspamd
A side-by-side editorial comparison of Stoat and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
Stoat vs Rspamd: at a glance
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.
What is Rspamd?
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
Stoat vs Rspamd: editorial side-by-side
Stoat
5.0COMMS
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.
Rspamd
5.0COMMS
Rspamd 4.3 fixes SPF evaluation order and rejects weak DKIM keys, with results that change.
◆ Current state
Rspamd 4.3.0 on November 13 is a correctness release with a long incompatible-changes list. SPF records are now evaluated in term order, closing a case where an explicit -ip4 deny could be overridden by a broader allow. DKIM rejects RSA keys under 1024 bits and signatures with duplicate tags, DMARC no longer drops a policy over an unknown tag, URL mismatches are scored apart from phishing, and PDF text extraction and archive unpacking change their output. Critical fixes cover a header line that could abort a worker from one unauthenticated HTTP request.
◆ Where it's heading
Since 4.1, every release has hardened parsers and closed memory-safety and trust gaps; 4.3 applies the same pass to the authentication standards themselves (SPF, DKIM, DMARC, ARC) and to content extraction. Operators should expect scores and fuzzy hashes to shift after upgrading, because the project now favours spec-correct results over backward-compatible ones.
◆ Prediction
A 4.3.x point release fixing regressions from these behaviour changes is the likely next step, as 4.2.1 followed 4.2.0 within two weeks.
