When properly configured, Postini is the best protection available for businesses from unwanted items introduced through E-mail. Among many other benefits, the top two things that Postini can immediately protect business from are SPAM (unsolicited commercial E-mails) and viruses.
Postini has SPAM filtering that is second to none. It is able to correctly filter many items that would make it through other filters and also has significantly less false-positives (incorrectly labeling a desired E-mail as SPAM) than other SPAM filters available. Granted, no SPAM filter is perfect and some E-mails are marked as SPAM that are not and other SPAM E-mails do make it through the Postini system, but there are also ways to prevent these from happening with the same types of E-mails. You are able to add an E-mail address as a “Safe Sender” in the Postini settings of your E-mail account so that it will never be blocked. You can also submit the headers of an E-mail that is SPAM that makes it through to increase the filtering capabilities of Postini for prevention in the future of that type of SPAM of getting to your Inbox.
Viruses are also blocked with excellent success. If an E-mail has a known virus in it, you may never even see it (depending on the settings your Administrator has set for Postini). You still need to have anti-virus software installed on your computer because E-mail is not the only way that you can receive a virus, but with the Postini service, your chances of getting a virus through E-mail is drastically reduced. Similar to SPAM, no filter is perfect and you could receive a virus in an E-mail sent to you but your chances of getting a virus without Postini is much higher than getting one that is not correctly filtered.
Besides your own personal settings for E-mail, there are also settings that your Administrator can configure for your entire E-mail domain. You may not even realize how much SPAM and viruses are even blocked because your Administrator can place additional filters that will keep E-mails from even reaching your personal Postini account and are rejected immediately. Along with setting additional filters, your Administrator has many other things that can be used for protecting your systems from unwanted E-mail.
