Communications provided via e-mail, instant messaging, chat, and web-based telephony applications, are monitored and restricted at a computer host. In one approach, messages from unknown or unsafe senders are intercepted and stored in a location inaccessible to all but an authorized person, until they can be reviewed by the authorized person, such as a parent. Via a user interface, the authorized user can review the messages at a later time to determine if the intended recipient, such as a child, should be able to access them. Once access is authorized, the stored messages are retrieved and provided to the recipient. In another aspect, a shared allow/block contact list identifies a user having different user names from one or more service providers. The contact list can integrate users from different services and communication modes. In another aspect, notification of monitoring is provided in the monitored messages or in newly generated messages.
