Free no spam list software for windows

No rooms List Manager is a managing tool for your MSN Messenger contact list. For example, you can delete unnecessary entries to sign in quicker than usually.
Often, when u sign in to Messenger, the server sends a list containing the
users who have permission to see you online (Allow List), who do not have
permission (Block List), who have you on their contact list (Reverse List),
and who you have on yours (Forward/Contact List).
Sometimes you delete some users, and people delete you from their list, too.
Even though they dont have you on their list anymore, their email will stay
on the list of people who can see you online. Why allow them to see you online,
if they dont have you on their list anymore? It is pointless to give them
persmission to see your status when they dont have the ability to do so.
In a different scenario, lets say you block someone and then delete that user
from your list. Imagine that the person you blocked also deletes you. Their
email will stay in your block list, even though it is not likely they talk to
you, because you are not on their contact list anymore.
You can clear your account list of these useless contacts using the Clean Lists
function, located under the "Lists" menu. Each email you delete will remove
about 20~30 characters from the data sent when receiving a new list.
You can also enjoy other functions, like searching for a contact, or manually
managing your lists (intended for power users).
Note: The first time you sign in after having used the program it might take a
little bit longer than usual, but that is because the Messenger Client is
downloading the new, shorter list. But after that signing in should always
be faster than usual. :)
