My DSL provider, Mindspring, blocks port 25 and I am quite happy about it. Of course send-pr doesn't work out of the box, but you can configure everything to work through their mail server. Blocking one port is very far from blocking all ports except 80, it's a bad analogy. This measure is directed at a very specific kind of activity (spamming) and does not affect vast majority of the users.
