There were a few bugs in Sendmail's TLS handling around 8.14 that can
cause this very issue, though I'm still at a loss as to why its
happening on a server with TLS disabled.  It may be you are correct,
and Evolution is sending STARTTLS and looking for the command to be
rejected, instead of verifying that the server even offers it as an
option.  Either that of the starttls error is a red herring, and
something else is wrong.  (I found one article saying that not having
the authentication username filled in might cause this error.)

A wireshark capture of the TCP session would be very interesting, I think.
