Blocking because a system/netblock has made many attempts to send=20
to non-existant users makes sense.

Any single address from wich a certain number of such attempts is=20
done during a the last n minutes are blocked with a tenporary=20
failure here. Netzero might well be doing something similar.

Of course it is also possible that they block in a way that=20
doesn't make sense.

Without knowing what your system(s)/netblock did to their=20
system(s), what made them block you, and how long the temporary=20
period is, it's impossible to judge wether it makes any sense or not.
