Postini sits between the Internet and your email gateway which can be an inhouse mail server or outsourced to Profitability.net. Email threats are preemptively stopped before messages reach your inbox. Since there is no installation or distribution of software or appliances, there are no worries about conducting frequent updates or version control issues.

Why should I purchase email filtering from Profitability.net?

We partnered with Postini 3 years ago to protect client email. As part of our service we often troubleshoot filter settings and assist clients in using the service properly. As a bulk reseller, we can also offer low prices that our clients appreciate.

Is Postini more effective than an appliance?

This is difficult to measure, but we believe that an outsourced service is more effective. IT resources are already busy focusing on other responsiblities. With Postini, you gain access to a dedicated team and a substantial infrastructure that is managed 24×7 with the sole priority of protecting your email. As an IT manager, you don’t have to worry about spam or virus outbreaks when you are on vacation because Postini is monitoring their systems 24×7 and adjusting the filter as needed to protect your email.

How long are messages stored in the filter?

Postini stores messages for 14 days or until they are delivered or removed by the user.

What is email spooling?

Spooling is the term used to capture email and store it until you reach quota or release messages from your storage area. Spooling is an optional add-on service that many clients use to prevent email from bouncing during mail system maintenance or loss of LAN connectivity to the office. Spooling can be purchased in blocks of 100MB of storage for $25 per month each. The spooling manager enables users to automatically release messages when a server is back online and define how long a system should be unavailable before spooling begins.

We don’t want to filter all of the email, can Postini deliver unfiltered messages for specific mailboxes?

Yes. Any mailbox or alias that does not exist in Postini will not be filtered and will be automatically delivered to your local mail server.
