Metasploit contains dedicated auxiliary modules designed to test SMTP server configurations safely and systematically.
HScan 1.2 is a legacy multi-port and protocol scanning tool that was popular in the early 2000s for network security auditing and vulnerability assessment. While it is often discussed in historical cybersecurity contexts, it is now largely obsolete and frequently associated with outdated "grey hat" activities.
If you need to scan for SMTP vulnerabilities or open relays today, use Nmap scripts ( --script smtp-open-relay ) which are safer, updated, and legal for authorized testing.
Connecting to the SMTP service to read the server's welcome banner. This metadata often leaked the specific mail server software (e.g., Sendmail, Postfix, Microsoft Exchange) and its exact version number. Smtp Scanner Hscan 1.2 Download
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.

A free demo is typically restricted to legal entities and requires company details (such as an INN) for a license. If you need to scan for SMTP vulnerabilities
: Threat actors know that people searching for "hacking tools" often disable their antivirus software to run them. This makes the downloader an easy target. The Legal and Ethical Landscape

The module auxiliary/scanner/smtp/smtp_version identifies the exact mail software running. Smtp Scanner Hscan 1
The module auxiliary/scanner/smtp/smtp_enum safely checks for valid users without risking system stability. 3. Manual Telnet/Netcat Auditing
"Hscan" (specifically version 1.20 or similar) is an old, legacy vulnerability scanner originally developed for identifying weak passwords or open services like SMTP, FTP, and Telnet.
Turn off VRFY and EXPN commands to prevent attackers from harvesting valid email addresses.
: Turn off these commands in your SMTP configuration (e.g., Postfix, Exchange) to prevent attackers from harvesting user email accounts.
