SlickText vs Rspamd
A side-by-side editorial comparison of SlickText and Rspamd — release velocity, themes, recent moves, and the top alternatives to consider.
SlickText vs Rspamd: at a glance
What is SlickText?
SlickText's feed is all SMS buying guides; no product release has surfaced since RCS.
SlickText's recent feed is entirely search content: SMS segmentation, church and nonprofit texting comparisons, Black Friday tactics, cost breakdowns and guides on annual plans. No release appears in the entries since the basic RCS addition.
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.

SlickText
5.0COMMS
SlickText's feed is all SMS buying guides; no product release has surfaced since RCS.
◆ Current state
SlickText's recent feed is entirely search content: SMS segmentation, church and nonprofit texting comparisons, Black Friday tactics, cost breakdowns and guides on annual plans. No release appears in the entries since the basic RCS addition.
◆ Where it's heading
The content is getting more explicit about buying decisions. Vertical comparison pages, published prices and an outgrown-your-platform pitch all aim at people ready to switch. Product motion cannot be read from these posts.
◆ Prediction
Expect Black Friday content through November and more vertical comparison pages. These entries give no evidence of how RCS is progressing.
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.
