In email messages, headers contain the addresses of all the computer systems that have relayed a message in between the sender and you. Each computer that forwards the message along its route adds a line of information to the headers. Usually you do not see the full headers, as they can be fairly long and so are not displayed along with the common "From:", "To:", "Subject:", and "Date:" headers. The information provided in the full headers allows you to determine where a message actually came from, and how it got to your computer. This is sometimes necessary because the address you see on the "From:" line can be spoofed, or faked.

Usually this information is important to determine/block spam/phish emails being seen on the network. You can help by sending this information to itsecurity@listserv.syr.edu. The information can be forwarded in following ways:-

 

SEND AS ATTACHED OUTLOOK MESSAGE:

If you suspect a message to be phishing/spam, please attach it as "Outlook Item" to a mail (as shown in Step 1,2,3 below):

 

ALTERNATIVELY MAIL THE FULL HEADERS OF THE EMAIL :
