Still doesn't work. I put some (message ...) to see the value of some
variables during the execution of smtpmail-send-it and I think the
problem is possibly somewhere else.

smtpmail-code-conv-from is nil and the return value of
(coding-system-change-eol-conversion ...) is also nil right after the
function call of (set-buffer-file-coding-system ...) that you modified
in your patch.

In the body of the very first let in smtpmail-send-it, just after the
varlist, the enable-multibyte-characters is nil, and thus
smtpmail-code-conv-from is also nil. But the global vaule of
enable-multibyte-characters is t. Do you think it helps anything if I
investigate where enable-multibyte-characters is set to nil?

Here is the mail I wanted to send, the saved mail file and the trace of
SMTP:
