  • src="cid:0000......What is this?

    I'm opening up a few emails on the Exchange server, most of which are spam. A lot of spam these days are images only, so I'm looking into the Source Code of the emails and keep finding something similar to this:
    <DIV><FONT face=Arial size=2><IMG alt=rail hspace=0
    src="cid:[email protected]" align=baseline
    border=0></FONT></DIV>
    How does the server know that CID is an image and where does it go to find it?

    The image is embedded.
    The CID: bit references the image that is embedded in the email message and tells the email client how to find it.
