FAQ

Common questions about Email Encryption Analyzer.

What log formats are supported?

The analyzer works with common SMTP server log lines that include connection events, STARTTLS commands, TLS handshake results, MAIL FROM, RCPT TO, DATA, and status codes. Postfix, Exim, and similar text-based logs are supported.

How does it determine if a session is encrypted?

It looks for STARTTLS commands followed by successful TLS handshake lines (for example, 'TLSv1.2 handshake successful'). Sessions with mail transactions but no TLS handshake are flagged as plaintext.

Are my logs sent to a server?

No. All analysis happens locally in your browser. Your SMTP logs never leave your device and are not stored anywhere.

Can it detect weak TLS versions?

Yes. The report lists the TLS versions found in handshake lines, so you can quickly see if deprecated versions like TLSv1.0 or TLSv1.1 are still in use.

Is this a replacement for a full email security audit?

No. It is a fast triage tool to highlight encryption gaps in SMTP logs. Use it alongside your broader compliance and security review processes.
