Both are fine, if your client stops if STARTTLS doesn't work/isn't

(Otherwise if an interceptor could remove the STARTTLS support
announcement from the server, and if the client continues in
non-encrypted mode, then it would be bad. smtpmail does the right thing,

  "starttls to insist on STARTTLS"
