Still it can be reduced to "\n\nFrom ".

You normally use MIME. The other MBOX things (MBOXO, MBOXRD iirc)
are very much unreliable. And they all change the message
checksum. But note i had to reintroduce >From for the "do _not_
use content-transfer-encoding" cases on user request. There are
still people who do not want MIME. Of course they cannot get
around it when they sign their messages.

You normally enforce a content encoding.
Doesn't mailman drive people insane by enforcing base64 encoding?
Some bell rings here.
