CAUTION: This E-Mail header analysis tool assumes all mail servers and clients in the transmission
path are trustworthy. It does not attempt to detect forged e-mail headers. Forged headers are common in spam
and other malicious e-mail, therefore this tool cannot be relied upon to accurately identify the source of such messages.
