Follow on Google News | CanIt 7.0 Anti-Spam Software ReleasedRoaring Penguin Software upgrades their CanIt line of anti-spam software for ISPs, Web Hosts, Universities, and Managed Services Providers.
By: Roaring Penguin Software Major new features in CanIt 7.0: 1. Outbound Rate Limiting CanIt can automatically block senders who send too many messages per hour. This allows system administrators to protect the reputation of their networks from compromised computers spewing spam. When a sender's outbound e-mail volume exceeds the hourly rate limit, the sender is stopped from sending any more e-mail and notifications are automatically sent to the email administrator. 2. CanIt-Reputation Block List The CanIt Reputation List collects IP reputation data from a worldwide network of sensors. Roaring Penguin aggregates this data into four DNS-based block lists: Spam Source: A list of IP addresses that have sent mostly spam and very little non-spam. Dictionary Attackers: A list of IP addresses that have sent to many nonexistent recipients and very few valid recipients. Greylist Stumblers: A list of IP addresses that have been thwarted by greylisting. Such machines are typically compromised personal computers. Good: A list of IP addresses that have passed greylisting, have sent to very few nonexistent recipients, and have sent mostly non-spam. These machines are very likely legitimate mail servers. 3. Multiple Hierarchical levels of Administrative Control CanIt-Domain- CanIt 7.0 is available as: CanIt-PRO, an anti-spam / anti-virus appliance or a soft appliance. CanIt-Domain- Hosted CanIt, a fully outsourced anti-spam solution.
