Rspamd vs VerneMQ
A side-by-side editorial comparison of Rspamd and VerneMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Rspamd vs VerneMQ: at a glance
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.
What is VerneMQ?
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.

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.
VerneMQ
2.5COMMS
VerneMQ follows its year-in-the-making 2.2.0 with a quick round of subscription fixes.
◆ Current state
VerneMQ releases infrequently; 2.2.0 on August 9 gathered about a year of cluster and connection work, including a socket-counting fix under rapid reconnects and faster inter-node readiness checks. 2.2.1 on October 16 followed with fixes for stale shared subscriptions after trie restarts, enforcement of non-zero message ids, and new webhook connect options.
◆ Where it's heading
Two months between 2.2.0 and 2.2.1 is quick for this project, which suggests 2.2 is getting active maintenance. The work stays inside the broker: subscriptions, clustering and protocol correctness rather than new features.
◆ Prediction
Further 2.2.x patches are more likely than a new minor; the feed gives no sign of 2.3 work.
