This is indeed the common way MIME aware mailers do it. (Though we, in the sense of the MLs i am subscribed to/track, had a trend to encode anything in base64 some time ago.) About strictly necessary, well, the POSIX standard and many simple tools, including "all" traditional BSD Mail / Unix mail go for the plain "^From " sequence, and even though RFC 4155 is much more specific about the "From_" line content, and all MTAs i have seen honour this, i think it is for the better to create message entries which the old tools and simple shell and awk scripts cannot get wrong, and this is what we do.
