Refolding a field is ok as long as you know the sematics of it. Ie.
you can and should refold Subject or Organization header fields,

Then it will interpret it as unstructured as it shoud, but it
should probably _not_ try to refold.

wouldn't it be safe to fold at white-space anyway?

Not if the unknown field is structured and it allows quoted-string 
somewhere. I don't exactly remember the rules for folding in quoted 
strings, but there was a possiblity to express linebreaks with 
quoted-strings - ah, no that was with the \CRLF construct.

So yes, you're right, folding at whitespace should then be save.
