No Spam Today! for Servers Freeware 3.1.4.2

NoSpamToday! is a e-mail spam filter (SMTP/POP3) compatible to every known mail server software. The flexible filter pipeline architecture allows combining the award-winning SpamAssassin filter, an attachment blocker, a remote blacklist filter (DNSBL), a delay filter, whitelists and blacklists to a filtering configuration that exactly suits your needs. The filter pipeline also allows integrating 3rd-party virus scanners, or any other filters you may wish to provide yourself.
Traffic limiting protects your mail service from flooding or directory harvest attacks. Recipient addresses can be checked while a message is submitted, avoiding the backscatter problem caused by some mail servers trying to send non-delivery notifcations to forged sender addresses.
With NoSpamToday! you have online access to view statistics charts and reports in real-time using a web browser, or using the NoSpamToday! admin application. Data available online includes spam statistics, mail logs (a listing of mails received, including subject, sender and recipient address), and a ranking of spam hosts (hosts submitting spam mails ie. in the last 24 hours).
The user interface is designed to allow easy, fool-proof configuration. Configuration changes are validated before they are accepted, and the user receives a warning before he can make a configuration error.
NoSpamToday! is available as freeware for personal and non-commercial use. A range of commercial licenses is available, offering exceptional value at low prices. The purchase of a license includes maintenance and updates for 12 months. Renewal licenses are available at a discount. Communities or non-profit organizations please inquire for special discounts.

Requirements: 800MHz CPU, 512MB RAM
