About

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.
