Advanced SMTP Cracker — Auto Detection, Auth Testing, Relay Check & Async High Speed (Windows)

A professional SMTP Probe & Checker tool built with Python AsyncIO, designed to detect, test, and validate SMTP servers at scale — without unnecessary email abuse.
This tool automatically discovers SMTP hosts using MX records, provider patterns, and common endpoints, then tests secure connections via SSL (465) and STARTTLS (587). It detects available authentication methods such as LOGIN, PLAIN, XOAUTH2, and can also identify relay capabilities.
For deeper validation, the tool supports both connect-only diagnostics and real authentication / email delivery testing, saving results in real time into clean, categorized output files.
Optimized for speed, stability, and safety, the AsyncIO engine ensures high performance while preventing hangs and legacy server issues. The application is compiled into a portable Windows EXE, requiring no Python installation on the target system.

Bulk SMTP probing & checking (hundreds of entries)
Auto SMTP host & mode detection (Auth / Relay)
