Mail filters can be installed by the user, either as separate programs (see links below), or as part of their email program (email client). In email programs, users can make personal, "manual" filters that then automatically filter mail according to the chosen criteria. Most email programs now also have an automatic spam filtering function. Internet service providers can also install mail filters in their mail transfer agents as a service to all of their customers. Due to the growing threat of fraudulent websites Internet service providers filter URLs in email messages to remove the threat before users click. Corporations often use filters to protect their employees and their information technology assets.
