Sigint email header

A SIGINT email header!

SIGINT stands for "Signals Intelligence", which is a type of intelligence gathering that involves the interception and analysis of electronic signals, such as communications, radar, and other forms of electromagnetic radiation.

In the context of email headers, a SIGINT header is a type of header that is used to identify and track email messages that are suspected of containing malicious or illegal content, such as spam, phishing emails, or malware.

Here is an example of a SIGINT email header:

X-SIGINT: 1234567890
X-SIGINT-Reason: Suspicious activity detected
X-SIGINT-Category: Phishing
X-SIGINT-Source: [email address of sender]
X-SIGINT-Target: [email address of recipient]

The X-SIGINT header is used to convey information about the email message, such as:

• X-SIGINT: A unique identifier for the email message.
• X-SIGINT-Reason: A brief description of why the email was flagged as suspicious.
• X-SIGINT-Category: The category of the suspicious activity, such as phishing or spam.
• X-SIGINT-Source: The email address of the sender.
• X-SIGINT-Target: The email address of the recipient.

Email providers and security software use SIGINT headers to identify and block suspicious emails, and to provide additional information to users about the emails they receive.
