Mail header analyser

A mail header analyzer is a tool that examines the headers of an email message to extract information about the sender, recipient, date, time, and other details. Here are some common features of a mail header analyzer:

  1. Header parsing: The tool breaks down the email header into its individual components, such as the From, To, Subject, Date, and Message-ID fields.
  2. Header analysis: The tool analyzes each header field to extract relevant information, such as the sender's email address, the recipient's email address, the date and time the email was sent, and the email's subject line.
  3. Domain analysis: The tool can analyze the domain names mentioned in the email headers to identify the sender's and recipient's domains, as well as any intermediate domains that may have handled the email.
  4. IP address analysis: The tool can extract IP addresses from the email headers, such as the IP address of the sender's mail server and the IP address of the recipient's mail server.
  5. DNS analysis: The tool can perform DNS lookups to resolve domain names and IP addresses, providing additional information about the sender's and recipient's networks.
  6. Spam and phishing detection: Some mail header analyzers can detect spam and phishing emails by analyzing the headers for suspicious patterns and indicators.
  7. Forensic analysis: Mail header analyzers can be used in forensic investigations to analyze email headers and reconstruct the email's transmission path.

Some examples of mail header analyzers include:

  1. Mail Header Analyzer (MHA): A free online tool that analyzes email headers and provides detailed information about the sender, recipient, and email transmission path.
