About Email Header Analyzer
Email headers are the lines at the top of a message that record who sent it and which mail servers handled it. This analyzer unfolds wrapped lines, shows the main fields, lists the Received hops from the first server to the last with the delay between them, and reads SPF, DKIM, and DMARC verdicts from the Authentication-Results header. It reports what the headers say. Headers added before the final server can be forged.
