I'd have to point him to an RFC implicitly or explicitly forbidding it. I couldn't find any such statement in RFC 2045 ("MIME"), and neither in

Look closer. RFC 2045, section 6.2, page 16:

"Thus there are no circumstances in which the "binary" Content-Transfer-Encoding is actually valid in Internet mail."

Can't get any more clear than that.

Oh dear. I had read section 6.2 (among others) of RFC 2045 in another context recently, but stopped on page 15 and skipped the rest of the section. I should have re-read it completely -- please excuse my ignorance, and thanks for pointing me in the right direction.

On a related note, for anyone who's interested: there seems to be an experimental SMTP extension for sending binary MIME messages (RFC 1830[1]).

I believe Sam was saying that the encoding *name* of "binary" is invalid, not specifically that binary content is the problem. [...] The proper encoding name, IIRC, would be "8bit" -- or maybe it's "8-bit", but I think the hyphen is not used.

Actually, there *is* a CTE type of "binary", next to "8bit".
