No, blocking a port does not restrict a customers use of the network
any more than one way streets restrict access to downtown stores. It
just forces certain traffic directions in a bicycle/motorcycle/car/van/
truck neutral manner. Carry anything you want. Others laws restrict
incendiary content.

It does block incoming SMTP traffic on that well known port.
I think the relevant neutrality principle is that traffic is not
blocked
by content.
My personal definition doesn't quite gel with that. You're deciding
for the
customer how they can use their connection, before you have any
evidence of
nefarious activity.
Would you consider restricting a customer's outgoing port 25 traffic
to a
specific mail server a step over the net neutrality line?
