How to Get Email Headers – A Guide from MxToolBox

When reporting spam that slips past the filters, it is essential that we receive the full message headers from a message. Additionally, sometimes our Support department may request the full headers from an email message in order to troubleshoot mail delivery problems. Please follow these instructions to obtain and forward full message headers to support@mxtoolbox.com.

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:

Note: Please put a short but descriptive note in the subject or the body of the message so we can quickly assess your issue or problem.
