Email containing cid

Did you ever receive an email containing a line that looks like this:

[cid:163091419@01122009-2514]

This probably means that something, in my case an image, is attached to the mail or embedded in it, but the email client, isn't able to process it correctly. There's an easy way to still visualize it.

Just open the email source and find the correct mail part, this should look something like this:

------=_Part_42520_1491296619.1259746973647
Content-Type: image/png; name="Picture 9.png"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="Picture 9.png"

Once you've found this you'll know what the type and encoding of the missing attachment is. Now you'll just need to select the block of encoded text, drop it in a suitable decoder, save the result as a binary file and hey presto!
