 I'll agree with you on one thing, though -- the whole
business of port 587 is a bit silly overall...why can't the same
authentication schemes being bandied about for 587 be applied to 25,
thus negating the need for another port just for mail injection?

Because that would require providers to act like professionals

I don't see what the big deal is. mx.justthe.net, for instance, requires 
SMTP AUTH on port 587 for everyone and requires SMTP AUTH on port 25 for 
anyone attempting to relay mail outside my network.

The biggest cost I can see, and it *is* a significant cost, is walking 
users through the process of configuring their MUAs to do the 
authentication. Configuring the servers, however, shouldn't be a huge 
problem, and you can mitigate the cost issue by only setting up 587 for 
people who need to have it set up.
