I know the reason, but that doesnt make it any better for me :)

Unfortunately, in the real world, this isnt an option. End users in Holland
are very aware of any kind of filtering, and start shouting censorship
when you filter UDP port 31337, let alone port 25. It would indeed solve
a lot of problems, but I doubt many dialup ISPs filter this port. If any
do, please say so, and share your experiences.
