SMTP:
There isn't really a problem letting others use this. The only reason it
isn't completely open is to keep spammers from using it to cover their
tracks. All users of your ISP have access to this server.
NNTP:
Again, no problem. The only reason for restricting it is to keep it from
being overloaded by outsiders. All users of your ISP have access to this
server.
POP3:
This *should* be authenticated, since it provides access to your private
mailbox. Some implementations allow "anonymous" access to certain kinds
of public messages, but if the server is allowing access to your mailbox
based on IP address alone, your ISP needs counseling.
URLs:
You'd have to be more specific.
Perhaps this is all just a sneaky way to make sure you don't share the
connection. :-)
