I understand!
If the mail has the form:
/-----------------------------example one-----------------------------
|FROM: hfljfl
|TO: fjdslkfjsd
|
|body of message gklglkdfjglkdfsjlgkjsdfgl
|???????????????????????????????????????????????????????????????????????
|more stuff
›------------------end of example--------------------------------------
Then it gets through.  But if it has the form:
/---------------------example two-(BAD)--------------------------------
|FROM: fhdljfhsdkl
|TO: fhljksdfhsdjkl
|
|body of message.osdfasdhlfhasdljkhflkajsdhglhaskljgh
|=======================================================================
|more stuff vkljlksfk
›------------------end of example---------------------------------------
 
Then it breaks it up into
    1) The part before the ==========
    2) The part after the ===========
 
 
Right? no? yes?
