Do they get much spam?

At the Swedish Government, they still use pneumatic tube system for transporting paper and stuff. Of course, they should not use as much paper as they are using, but I guess when they do (and because they are), a pneumatic system is a good tool.

After looking in Google, I find there are many manufacturers (still). So this survived X.400. Interesting…I ask myself how much spam they get? The menue from the local lunch restaurant?
