The script processes an input source (e.g., emails.txt or combo.txt).
Ensure these legacy commands are disabled on your public-facing mail relays. MailKeker.py can often fall back to these if the RCPT TO method is blocked.
MailKeker.py is not inherently malicious; it is a tool of revelation. For defenders, it exposes the uncomfortable truth that SMTP, a protocol designed in 1982, was never built for privacy. The ability to verify email addresses silently is a feature, not a bug, of the Simple Mail Transfer Protocol.
If you are a system administrator, download MailKeker.py tonight and run it against your own domain. The results may be alarming. If you see that your server silently confirms the existence of every rcpt to, you have work to do. If you are an attacker, be warned: modern email security gateways (M365 Defender, Proofpoint, Mimecast) utilize machine learning to detect the specific fingerprint of RCPT TO enumeration scripts like this.
Ultimately, MailKeker.py serves as a reminder that in cybersecurity, the best way to protect a door is to first know exactly how easy it is to knock.
