This happened to me a couple of weeks ago too.  I'm not sure how to tell
postfix to use port 587 or even if that is a good solution.  My solution
for now is to just relay everything through Rogers' (Yahoo's) mailserver.

Changes I made (Debian):

- apt-get install postfix-tls
- added to /etc/postfix/main.cf:

    smtp_sasl_auth_enable = yes
    smtp_sasl_security_options =
    smtp_sasl_password_maps = hash:/etc/postfix/sasl/.passwd
    relayhost = [smtp-rog.mail.yahoo.com]

- /etc/postfix/sasl/.passwd looks like this:

smtp-rog.mail.yahoo.com     rick.delaney-bJEeYj9oJeDQT0dZR+AlfA at public.gmane.org:my_password

  You need to run 

        postmap hash:.passwd

  on it.

- restart postfix.

HTH,
