Frequently asked questions

How do I trace the real origin of an email?

By analyzing full headers and relay path, not only the visible “From” line.

What is email spoofing?

It is impersonation where sender identity appears legitimate while origin is fraudulent.

Why can “From” differ from technical headers?

“From” is user-facing text, while technical headers reveal actual routing and authentication evidence.
