Yet another reason for supporting port 587 on your servers for remote
authenticated mail submission from your users.  If you don't support
port 587, and use SPF, it may break when AOL or other providers re-direct
port 25.

Has AOL notified anyone in advance?  Quite a few provider-independent
mail providers were caught by surprise.

        Is there a mailing list that will reach all/most of these
        provider-independent mail providers?

        (If so, then that's where we should be having this discussion
        asking why they don't support port 587 yet.)
