Please don't ever suggest blocking port 587. Using port 587 is the solution, not part of the problem.
Don't get me wrong, outbound spam filtering is a great idea, but it should be done by the MSA, not at the ISP level as ISPs have no clue as to what type of activity is legitimate or not for a particular user.
