How to read a .EML file in vb.net

EML file is very reasonable; unlike many other format for mail messages, this is exactly the single-message package which is actually transmitted through the mail system.

As to the encryption — I doubt it. If the recipient of the message can read it you can do it, too, unless the two performed key exchange in the past (in which case, you would not be able to decrypt anything even if you spied on key exchange, in case of proper encryption technology).

Maybe, post the header of the "encrypted" part and the beginning of the "encrypted code" itself. I suspect it's not the encryption...
(Use "Improve question".)

Header! where is the header before it?
