Account implemented (ACCT), the client will internally keep state of the account information specified throw SetAccountData or a direct call to Account. Authentication will be able to use the account information to continue a login sequence ending in a status of Status.AccountForLogin, or fail generating an error if no account information is available/the acct command fails.
HOST implemented (support for virtual hosts), throws an error if a user is authenticated and REIN command does not work to reinitialize connection
