Retrieve Complete Headers from an Email

Sometimes Wharton Computing or Wharton’s Information Security Office will ask you for the headers of an email to support a technical issue (for example when emails are being blocked by our spam filters or anti-phishing services) or to support a security-related matter.

For more information about headers and their function, see Penn ISC's information on Email Headers.)


Unfortunately, simply forwarding an email to your Wharton Computing representative will not include the email’s original header information. Instead, you'll need to follow the directions linked below for the email client you use to read your email.

Email Headers by Client

Each email client displays their complete headers in slightly different ways. Find your email client and use the links provided for directions on copying email headers.

If you don't see your client listed, see ISC's Email Header section on Other Email Clients.
