Viewing Mail Headers

When talking about the “full headers” of an email we are referring to the complete header information that is contained in each email you send. These headers are generally not seen by the user because their content is technical and is not usually of interest to the user. Sometimes, however, viewing the headers can be helpful, such as when you need more information about who sent the email and when.

In SOGO you can view this information by clicking on the email and clicking the three dots at the upper right corner. Then click View Message Source. This will display the full source of your email, including the complete header information.
