SMTP Test Tool
Cross-platform SMTP / IMAP / POP3 connectivity tester with IT-actionable diagnostics.
smtp-test-tool is a single static binary that lets IT teams verify SMTP / IMAP / POP3 connectivity, exercise STARTTLS / SSL / AUTH paths, and translate cryptic 5.7.x bounce codes into IT-actionable remediation steps. Ships with a CLI and a native GUI in one download; runs entirely on rustls (no OpenSSL); stores credentials in the Windows Credential Manager.
