Answered your own question. :-D

The translation between the SMTP stream's CRLF and the UNIX (or DOS
text-mode) LF is maybe done elsewhere?

Does ssmtp explicitly set stdin to be text-mode? If it's coming from a
UNIX background maybe not. Might be a simple fix then, to get it to do
so before starting to read?
