Some users may wish to see the complete email header attached to email messages in the Mail app for Mac OS X. These long headers can reveal many details about the sender of an email message, including the origin mail servers and IP addresses, original arrival time, email alias details, and much more, making them a potentially valuable resource for some situations, particularly for users wishing to authenticate the validity of an email or mail message.

Additionally, email header information can be very helpful for troubleshooting complicated email server issues. Note this is generally best reserved for advanced users who understand how to interpret the email header data, as the average user will likely just find the email header to be unnecessary gibberish that complicates an email message.

Again, the complete header detail data is not really meant to be interpreted by an average email user, this is generally best for advanced users who have some experience accurately interpreting and reading the header details, which often look like a bunch of hexadecimal nonsense, dates and times, server names, and IP addresses. But, as a general rule, users can determine if a message is authentic by reviewing the header for an email message and checking to see if the header information corresponds properly with who the sender claims to be.

If the sender information or claim within an email does not match up with the email header information, you may have reasonable suspicion that the sender is not who they say they are, but again, this is a generalization and that is not always true. Had enough viewing the complete header and want to return to the default header view in Mail for Mac? That is just as easy:. Most Mac users will find that having the full headers shown for email message is quite unnecessary, but it can be helpful to toggle the display of the complete header on temporarily sometimes to validate an email, or to help rule out problems with email servers, and then toggle the display back off to return to the regular email header view again.
