Email Header Analyzer

Our support department may request the full headers from an email message in order to troubleshoot mail delivery problems.
Every single Internet e-mail message is made up of two parts the header and the message body of the email. Every single email you send or receive on the Internet contains an Internet Header, a full and valid e-mail header provides a detailed log of the network path taken by the message between the mail sender and the mail receiver(s) (email servers).
Your email client program will usually hide the full header or display only lines, such as From, To, Date, and Subject, see below for more information on pulling headers for your email client. If you do not know where to find the email headers for your email client this blog has some good screen shots.
If you want to understand the headers you can copy them into this email analyzer and get a great deal of detail about an email.
