Definition - What does Postini mean?

Techopedia explains Postini
Postini uses sophisticated proprietary email scanning and pattern-gathering tools to analyze and classify email messages. However, even the service can sometimes erroneously classify email as spam, phishing attempts, and so on, and quarantine the email. In such cases, the client receives an automated alert, and can login to his or her account with Postini and release the message, as well as mark similar emails as "safe".
Postini also offers email archiving solutions.
