I’ve heard that I can view more information about where an e-mail
message came from, by viewing the “full headers” of the message. How
can I do that in Gmail?
Normally when you view an e-mail message in your inbox, it shows only the
“From” address, the “To” address (typically your address, but also including
anyone else the message was sent to), the “Subject” line, and the date sent.
The “full headers” can show more information about where the message was
sent from and what path it traveled before reaching your inbox.
Recent articles have explained
view full headers in Hotmail, for example. Gmail, confusingly, doesn’t make this
option easy to find, but here’s how to do it:
Start with an open e-mail message whose full headers you want to view. (Below is an
example of spam that I received, so I’m curious to see where it came from. For privacy
reasons, I’ve “scratched
out” the addresses of the senders whose messages are in my inbox.)
In the upper right corner of the message, to the right of the word “Reply”, is a box
with a downward-pointing arrow. Click that box:
and click the “Show original” option:
This will open up a new window displaying the full headers of the e-mail message:
What the full headers mean, and how to read them, is a much longer and more complicated
answer. This article just explains how to view full headers in Gmail, since Gmail makes
it far from obvious where to find that option!
Simply close that window when done viewing full headers.
