In detail

The package ships a licence file alongside the binary, and the stock config names it relatively (license.txt) — resolved against the configuration directory. Hub writes the absolute path. On our stand the console reports a production licence with no rate limit, which is what a licence governs: MailerQ's licences can cap messages per minute, and the console shows the cap on every screen. A node that quietly stops at a ceiling would show it there rather than in the logs.

What happens if you get it wrong

File missing or unreadable.The engine refuses to start; the node is silent and the reason is in the process log only.from the documentation · inference
