Rspamd vs RSS.com: 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 RSS.com?
RSS.com is adding reasons for podcasters to stay, from listener voicemail to a free academy.
RSS.com ships about one bundled release a month. The last two added listener voicemail (60-second browser recordings linked from every episode's notes) and a free Learning Center with 22 courses built from its own blog and video library. Last year's public API remains the biggest change to what the platform can do.

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.
RSS.com
2.5COMMS
RSS.com is adding reasons for podcasters to stay, from listener voicemail to a free academy.
◆ Current state
RSS.com ships about one bundled release a month. The last two added listener voicemail (60-second browser recordings linked from every episode's notes) and a free Learning Center with 22 courses built from its own blog and video library. Last year's public API remains the biggest change to what the platform can do.
◆ Where it's heading
With hosting itself a commodity, RSS.com is competing on what surrounds it: audience interaction, education for new podcasters, and open standards such as Podcasting 2.0 tags. The API gives technical users a way to automate, while the academy and voicemail aim at beginners.
◆ Prediction
The entries show steady monthly releases but no clear next feature, so the specific next move is unclear.
