Whitelists are used frequently with e-mail applications to allow users to compile lists of senders they wish to receive e-mail from. This list overrides any blacklists and spam filters, and allows the e-mails to be delivered to the users inbox instead of filtered out as spam.

A whitelist is a list or register of entities that are considered trustworthy, authorized, or allowed to access certain resources, use certain services, or perform certain actions. In computing and networking contexts, a whitelist typically specifies items (such as email addresses, IP addresses, domain names, applications, or users) that are permitted to access specific systems or applications.

Here are a few common uses of whitelists:

1. Email Filtering: Email systems often use whitelists to allow emails from trusted senders to byp*** spam filters.
2. Network Security: In network security, whitelists can define which IP addresses or ranges are allowed to access a network or specific services.
3. Software Applications: Some software applications use whitelists to specify which programs or scripts are allowed to execute, enhancing security by preventing unauthorized or potentially malicious software from running.
4. Web Filtering: Whitelists can be used in web filtering to specify which websites users are allowed to visit, restricting access to approved sites only.
