The standard firewall configuration is to block all traffic unless

Which RFC defines that "standard"?

 While it's true that most SMTP servers will accept port 587,
most firewall policies only permit inbound TCP 25 to an SMTP server.

"most" out of precisely how many you surveyed?

And the smtp server needs to know to treat 587 differently (clients
must be identified), so it should know to accept connections there.

 Call this overzealousness if you will, but it's a simple reality.

In which universe?
