MirrorFly vs Rspamd
A side-by-side editorial comparison of MirrorFly and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
MirrorFly vs Rspamd: at a glance
What is MirrorFly?
MirrorFly publishes a chat-API content farm; the product itself is invisible in this feed.
Every entry is search-targeted: clone-app build guides for Slack and WhatsApp, framework tutorials for Angular and React Native, competitor alternative lists for Vonage and Mattermost, and industry statistics roundups. None of it describes a change to the MirrorFly SDK, its APIs, or its self-hosted deployment.
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.

MirrorFly
5.0COMMS
MirrorFly publishes a chat-API content farm; the product itself is invisible in this feed.
◆ Current state
Every entry is search-targeted: clone-app build guides for Slack and WhatsApp, framework tutorials for Angular and React Native, competitor alternative lists for Vonage and Mattermost, and industry statistics roundups. None of it describes a change to the MirrorFly SDK, its APIs, or its self-hosted deployment.
◆ Where it's heading
The strategy is to own developer search terms around building messaging features, then convert that traffic into CPaaS evaluations. The recurring themes, self-hosting, source-code access, and on-premise security, tell you what MirrorFly sells against, namely hosted competitors that keep customer data on their own servers.
◆ Prediction
Expect more clone-app and alternatives content on the same rotation. This feed will not surface SDK releases unless MirrorFly starts publishing them somewhere it syndicates from.
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.
