How did you do that, precisely?

From etc/NEWS:

    *** SMTPmail now uses encrypted connections (via STARTTLS) by default
    if the mail server supports them.  This uses either built-in GnuTLS
    support, or the starttls.el library.  Customize `smtpmail-stream-type'
    to change this.

From C-h v smtpmail-stream-type:

    smtpmail-stream-type is a variable defined in `smtpmail.el'.
    Its value is nil

    Documentation:
    Type of SMTP connections to use.
    This may be either nil (possibly upgraded to STARTTLS if possible),
    or `starttls' (refuse to send if STARTTLS isn't available), or `plain'
    (never use STARTTLS), or `ssl' (to use TLS/SSL).

So maybe setting that to `starttls' will have the desired effect?
