Is this skill safe for production environments?

This skill should only be used on servers you own or have explicit written authorization to test, as some techniques can be intrusive or cause load.

Which tools does this skill require?

It utilizes industry-standard tools including Nmap, Hydra, Netcat, and the Metasploit Framework for deep security analysis.

Can this skill help prevent email spoofing?

Yes, it provides techniques to analyze SPF, DKIM, and DMARC records to ensure your domain is protected against spoofing.

What is the primary use of this skill?

It is used to perform comprehensive security audits on SMTP servers, identifying vulnerabilities like open relays and user enumeration risks.

How does it handle user enumeration?

It tests various SMTP commands like VRFY, EXPN, and RCPT TO to determine if the server inadvertently leaks valid email addresses to unauthorized users.
