Blocking the well known port 25 does not block sending of mail. Or the
message content.
Blocking various well know M$ protocol ports does not block remote
file access. Or control the type of files that can be accessed.
I think the relevant neutrality principle is that traffic is not
blocked by content.
So, no, blocking any port is NOT against the idea of Net Neutrality.
