Ergo vs Rspamd
A side-by-side editorial comparison of Ergo and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
Ergo vs Rspamd: at a glance
What is Ergo?
Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.
Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.
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.
Ergo vs Rspamd: editorial side-by-side
Ergo
2.5COMMS
Ergo keeps tracking IRCv3 upstream while quietly opening its history layer to real databases.
◆ Current state
Ergo ships roughly two releases a year, each announced as a release candidate about a week ahead of the final. The content is consistent: whatever IRCv3 specifications have firmed up since the last cycle, plus bug fixes and config-format adjustments. The one structural change in this window was pluggable history storage, which took Ergo off its embedded database as the only option.
◆ Where it's heading
This is a project with a stable release ritual and a narrow remit: be a modern IRC server that implements the spec correctly and runs as a single binary. Feature work arrives as specification support rather than product invention. The exception is the operational surface — history backends and the HTTP API — where Ergo has been steadily making itself easier to run alongside existing infrastructure instead of as a self-contained island.
◆ Prediction
The v2.19.0 final should follow its release candidate within a week or two on the established pattern; the config-format break flagged in that RC is the main thing operators will need to handle on upgrade.
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.
