SMTP Test
Connect to an SMTP server, optionally authenticate, send a limited test message, and return a redacted SMTP transcript.
Disclaimer
This tool performs active SMTP Connections. Only use it against systems you own or have explicit written authorization to test. Abuse may be illegal in your jurisdiction. This tool logs all tests including your IP address.
Note: For security, this tool employs rate limiting. Submitting too many request or failures may trigger a cool down period.
