BINARYMIME was defined in 2000 to avoid that issue, and invents a new BDAT
command that uses a byte count rather than escape sequence, so the message

icloud/me.com support it, Yahoo and AOL don't, but I've never seen client
software that would take advantage of it.
BINARYMIME is the preferred mode of operation for Isode's Android email client.
I hope others would follow.
