Display and transfer the headers of an email
This guide explains how to display and transfer the headers of an email.
What are the headers of an email?
An email consists of a header and the actual content of the message (body, main text). The headers of an email provide different information, such as:
- the sender
- the recipient
- the date
- the subject
- the servers involved when transferring the email between the sender and the recipient
Most messaging software packages do not display the headers directly, yet displaying or transmitting them allows the Infomaniak support team to identify the problems encountered.
Extract of email headers sent to an @infomaniak.com address:
Display the headers
To display the headers with kMail (Infomaniak webmail), possibly to copy them to the support team:
Open kMail (mail.infomaniak.com) then once on the email concerned:
- click on the menu at the top right of your email
- click on Display headers
To display the headers if you use an external email application, click here.
Transfer the email headers
To transfer email headers in response to a request from the support team or to a recipient of your choice:
- either your copy-paste the headers displayed using the above method,
- or you forward the email message
However, for the headers to be present, it is essential to forward the message not in the body of the message but solely as an attachment. The attached email will, in principle, be in .eml format and this file contains all the headers necessary.
