Smtp Scanner Hscan 1.2 appears to be an old/underdocumented SMTP-scanning tool (often referenced as “hscan” or “hscan (scan smtp)”) distributed via informal file-hosting and software-aggregate sites. Available traces point to small ZIP packages on file-sharing sites (4shared) and listings on generic download portals and software directories. There is scarce official documentation, uncertain provenance, and limited/versioned releases; some entries reference a Java-based “SMTP Proxy Scanner” or similarly named open-source projects but not a clear, authoritative Hscan 1.2 project page.
