Important point of grammar, it is either:

        - make connections (send) TO port 587
OR
        - accept connections (listen) ON port 587

The first two columns in the master.cf file specify the (listen)
endpoints at which you accept connections. This has nothing to
do with outgoing delivery.

This is an outbound delivery.

This is an incoming service port.

Most likely you want:

    main.cf:
        relayhost = smtp:[smtpauth.earthlink.net]:587
        smtp_sasl_password_maps = hash:/etc/postfix/smtp_passwd

    smtp_passwd:
            [smtpauth.earthlink.net]:587 yourusername:yourpassword

But, why run Postfix at all in this case, if your smarthost is an ISP MSA,
you should be using your MUA to send mail directly to the ISP. Forcing
an MTA to use an MSA service as a relay is needless pain and suffering.
