I uncommented the above line and added the following to main.cf:

smtpd_tls_security_level = may

as instructed here:

http://www.postfix.org/TLS_README.html#server_enable

and restarted postfix, but I still can't send.  In claws-mail, I tried
specifying 587 and I'm specifying Use SSL for SSMTP.  I'm guessing TLS
isn't set up properly?
