Which tools are required to use this skill effectively?

It leverages standard security tools including Nmap, Netcat, Hydra, smtp-user-enum, and the Metasploit Framework.

Can this skill test for email spoofing protections?

Yes, it includes procedures for analyzing SPF, DKIM, and DMARC records to evaluate a domain's resistance to spoofing.

How does it handle user enumeration?

It guides the user through multiple methods including VRFY, EXPN, and RCPT TO commands to identify valid email addresses on a target server.

What is the primary purpose of this skill?

It provides specialized workflows and commands for security professionals to identify and remediate vulnerabilities in SMTP mail servers.

Is this skill safe for production environments?

While useful for auditing, penetration testing can be intrusive; always ensure you have written authorization and follow ethical guidelines before testing any server.
