Conducts comprehensive security assessments and vulnerability testing for SMTP mail servers.
This skill provides an automated and guided framework for evaluating the security posture of SMTP servers. It assists users in identifying critical vulnerabilities such as open mail relays, sensitive information disclosure through banner grabbing, user enumeration via VRFY/EXPN commands, and weak authentication mechanisms. Designed for authorized security professionals, it covers the entire assessment lifecycle from initial service discovery and MX record analysis to advanced brute-force testing and encryption configuration audits, ensuring mail servers are hardened against unauthorized access and email spoofing.
