I built MailGate after getting tired of fake signups. Disposable emails, bot accounts, typo domains, all quietly polluting the DB. Most validation services need an API key and add network latency. MailGate runs entirely offline. 8,400+ blocked domains bundled in the package itself, combined with live MX checks and typo detection. What it catches: - Disposable providers (mailinator, guerrillamail, etc.) - Typo domains (gmial.com, yaho.com) - Bot-generated usernames - Domains with no active MX records - Parked domains Drop it into any Node.js app: const { validateEmail } = require('mailgate'); const result = await validateEmail(req.body.email); // result.action → 'ALLOW' | 'FLAG' | 'BLOCK' MIT licensed, zero dependencies on external APIs. Would love to hear what you think.
