It is the responsibility of the local delivery agent to ensure that the
stored email can be read by the mail recipient. If your MDA is going to
store your email in a format that allows confusion among messages then it's
your MDA's responsibility to ensure such confusion doesn't happen.
One POSSIBLE exception to this would be that the sender of a clear-signed
email (e.g., RFC 2015 multipart/signed) may want to encode and "From "
lines in the body part covered by the signature to ensure that someone
down the line doesn't invalidate the signature by "From " mangling. RFC
2015 section 5 mentions this and suggests using quoted-printable transfer
encoding on the "F".
