To test SMTP relay and authentication weaknesses on Postfix or Exchange, run protocol-level assessments against the mail server. This identifies open relay abuse, forging capabilities, and authentication vulnerabilities across on-premises and cloud deployments using included test cases and payloads.

Open relay testing identifies mail servers that allow unauthorized email routing, which attackers exploit for spam or phishing. By probing SMTP protocols to detect relay abuse and forging capabilities, you can remediate misconfigurations and secure your email infrastructure.

Yes, you can check SPF, DKIM, and DMARC configurations during email protocol assessments. The skill tests these email security mechanisms to identify spoofing weaknesses and header manipulation vulnerabilities, ensuring proper email authentication across your mail servers.

Yes, this skill supports credential attacks against IMAP and POP3 endpoints, including Exchange. It performs protocol-level reconnaissance and authentication testing to identify weak credentials and authentication flaws in mail servers like Dovecot during network penetration tests.

The best way to test STARTTLS misconfigurations and certificate validation is through targeted protocol-level assessment. The skill checks TLS/STARTTLS configurations, validates certificates, and verifies cipher support to expose encryption weaknesses in your mail infrastructure.

You should not use email protocol testing without explicit authorization, as probing SMTP, IMAP, and POP3 protocols with credential attacks and relay checks can disrupt mail services. Ensure you have proper scope approval for network penetration tests and red-team exercises.
