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.

Acest proiect este un instrument de verificare a e-mailurilor care verifică dacă o adresă de e-mail există și poate primi mesaje fără a trimite un e-mail real. Oferă aceste capabilități printr-un API HTTP programatic și o interfață CLI locală. Sistemul se distinge prin combinarea verificării handshake-ului SMTP și a rezoluției înregistrărilor DNS cu un instrument de analiză a riscurilor care detectează adresele temporare, conturile bazate pe roluri și domeniile catch-all. Include, de asemenea, un agregator de metadate pentru a prelua informații publice de profil și imagini asociate cu o anumită adresă de e-mail. Suprafața de capabilități mai largă acoperă validarea livrabilității e-mailurilor, evaluarea riscurilor pentru a preveni înregistrările frauduloase și testarea conectivității SMTP. Serviciul backend poate fi implementat ca un serviciu în rețea folosind un model de deployment containerizat.
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.
