No, but widely enough that we've not had any complaints. It's even the 
default port used by some MUAs now - like Apple's "Mail.app" and the 
iPhone. Blocking port 25 will encourage deployment of port 587.

In my view, network operators should assume now that email service 
providers DO provide port 587, unless they have an overwhelming business 
case to do otherwise.
