Maddy vs Netcore Cloud: at a glance
What is Maddy?
A one-binary mail server learning to behave like production infrastructure.
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
What is Netcore Cloud?
Netcore's feed carries no releases - only the argument that marketing teams should hand work to agents.
This feed is Netcore's marketing blog, not a changelog: every recent entry is a buyer's guide, a category explainer, or a customer story, and none announce a shipped change. Read as positioning rather than product history, the material is consistent - Netcore describes itself as an engagement platform with production-ready AI agents, native Email, WhatsApp, RCS and Push, AI search and predictive analytics in one stack. Competitive comparisons against WebEngage and Bloomreach are the most product-specific posts here, and they argue channel ownership and ecommerce depth as the differentiators.

Maddy
0.0COMMS
A one-binary mail server learning to behave like production infrastructure.
◆ Current state
maddy is an all-in-one SMTP and IMAP server written in Go, aimed at people who want a working mail host without assembling Postfix, Dovecot and a policy daemon themselves. The 0.9 line moved quickly — 0.9.0 through 0.9.5 between late March and late May — with the sequence following a recognisable shape: a feature release, an immediate patch for a broken integration, a security release, then cleanup. Configuration is directive-based, and much of the changelog concerns the behaviour of individual modules like auth.ldap, check.rspamd and check.dnsbl.
◆ Where it's heading
The project is systematically removing the compromises that made early versions convenient. Obsolete SASL LOGIN was disabled by default, the STARTTLS plaintext fallback was dropped, the maddyctl symlink behaviour and the implicit run command were deleted after four years of deprecation warnings, and libdns providers that have not kept up with 1.x are being cut. Running the other way is operational maturity: no-downtime config reload, queue-length metrics, OpenMetrics fixes, systemd readiness reporting, and SLSA build attestations on release artifacts. This is a project moving from hobbyist-friendly to operator-friendly, and accepting breakage to get there.
◆ Prediction
0.10.0 is already scoped by the deprecations announced in 0.9.1 — expect the flagged libdns providers to be removed and gandi to require Bearer tokens. Given the 0.9.x pattern, a feature release followed quickly by an integration fix is the likely shape.
Netcore Cloud
5.0COMMS
Netcore's feed carries no releases - only the argument that marketing teams should hand work to agents.
◆ Current state
This feed is Netcore's marketing blog, not a changelog: every recent entry is a buyer's guide, a category explainer, or a customer story, and none announce a shipped change. Read as positioning rather than product history, the material is consistent - Netcore describes itself as an engagement platform with production-ready AI agents, native Email, WhatsApp, RCS and Push, AI search and predictive analytics in one stack. Competitive comparisons against WebEngage and Bloomreach are the most product-specific posts here, and they argue channel ownership and ecommerce depth as the differentiators.
◆ Where it's heading
The editorial line is moving from AI-assisted marketing toward agent-operated marketing - a holiday playbook framed around a team that never sleeps, a case study crediting Content, Scheduler and Insights agents with a 325% response lift, and repeated argument that campaign-based targeting is structurally too slow. Alongside it runs a unified-customer-data thread positioning the CDP as the substrate agents need. One post on the end of the email tracking pixel signals awareness that open-rate measurement is eroding under consent rules.
◆ Prediction
Because this source publishes no release notes, the product's actual shipping cadence is not observable here; the safe read is that Netcore keeps packaging existing capability as named agents rather than that specific features are imminent. Worth re-pointing the crawler at a genuine changelog before drawing product conclusions.
