Verification processes that use the Simple Mail Transfer Protocol handshake to determine email reachability.
Distinct from Handshake Validations: Specifically applies handshake validation to the SMTP protocol for email existence checks rather than general security headers.

Ce projet est un outil de vérification d'e-mail qui vérifie si une adresse e-mail existe et peut recevoir des messages sans envoyer d'e-mail réel. Il fournit ces capacités via une API HTTP programmatique et une interface en ligne de commande locale. Le système se distingue en combinant la vérification par handshake SMTP et la résolution d'enregistrements DNS avec un outil d'analyse des risques qui détecte les adresses jetables, les comptes basés sur des rôles et les domaines catch-all. Il inclut également un agrégateur de métadonnées pour récupérer des informations de profil public et des images associées à une adresse e-mail spécifique. La surface de capacité plus large couvre la validation de la délivrabilité des e-mails, l'évaluation des risques pour prévenir les inscriptions frauduleuses, et les tests de connectivité SMTP. Le service backend peut être déployé en tant que service réseau utilisant un modèle de déploiement conteneurisé.
Verifies email reachability and mailbox existence using the SMTP protocol handshake and DNS record resolution.
This project is a self-hosted email verification system and API designed to validate email existence and clean mailing lists on private infrastructure. It functions as a deliverability tool that confirms if email addresses are reachable by communicating with mail servers via the SMTP protocol without sending actual messages. The system is distinguished by its high-volume SMTP infrastructure, which utilizes a stateless worker architecture and message queue task distribution to scale validation tasks. It includes an SMTP proxy gateway that routes requests through SOCKS5 proxies to mask server i
Validates email existence by simulating the SMTP mail transfer protocol exchange without sending a full message.
Maddy is a modular mail server that assembles a complete email system by connecting small, single-purpose modules through a declarative configuration file. Rather than a monolithic stack, it lets operators compose message processing, storage, authentication, and security enforcement from interchangeable building blocks, with each module handling a specific function like receiving SMTP connections, verifying credentials, or applying policy checks. The server distinguishes itself through its flexible authentication and security architecture. It delegates user verification to external systems in
Accepts email messages through SMTP, LMTP, or Submission protocols, optionally verifying sender credentials before processing.
