Host 99 spam protection system includes a unique combination of numerous effective filters such as Bayesian, Penalty Box, DNSBL/RBL, URIBL, SPF, HELO, PTR, MX/A, Clam-AV virus scanning, and more.

Our Spam System requires very little configuration; you do not need to continually update it with details of your email accounts, mailing list memberships, etc. Our system does this for you when you go about your daily email routines.

You can use this spam filter in conjunction with any other anti-spam tool you already use at your computer, if you wish. However, if you're like most users, you'll find that this entirely unnecessary. With ASSP alone, the amount of spam you receive in your inbox will be reduced by 90% or more!

If you're worried about false positives, every mailbox that you create includes a spambox (spam folder) in which 7 days' worth of spam messages is kept. It has long been clear to me that the best place to stop spam is at an organization's SMTP server.

This is true for the following reasons:

Most spam has an invalid bounce address, so notifying non-delivery simply bounces to Postmaster, creating even more wasted bandwidth. Failing to notify non-delivery is a problem for false-positives. The SMTP server is the only place where spam can be stopped before entering your system.

The only possible feedback for spammers to void an address is from the SMTP server. Spam that passes through your SMTP server into mailboxes incurs cost to your organization: storage, transmission, backup, deletion in all these ways spam costs you money. The only way to minimize cost is to reject it at the initial point.
