No, port 587/tcp is not used for "secure e-mail" (whatever that's supposed to be), but for e-mail submission. It's an attempt to separate mail relaying between SMTP servers from initial submission from the user's mail client to an SMTP server. Just as with SMTP, security is optional. See RFC 4409 for details on the protocol.
