CanIt 7.0 Anti-Spam Software Released

April 12, 2010 - PRLog -- 13 Apr 2010 – Ottawa, Ontario, Canada – The fight against spam just got easier as Roaring Penguin Software Inc., makers of the acclaimed CanIt-PRO, CanIt-Domain-PRO and Hosted CanIt anti-spam solutions, announced the release of CanIt 7.0.

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-PRO permits arbitrary levels of administrative control.  For example, an installation administrator has overall control.  He or she can delegate control over sets of domains to a regional administrator, who in turn can delegate control over some domains to site administrators.  Finally, site administrators can delegate control over individual quarantines and settings to end-users.

CanIt 7.0 is available as:

CanIt-PRO, an anti-spam / anti-virus appliance or a soft appliance.
CanIt-Domain-PRO , a version allowing MSPs to host anti-spam for their customers.
Hosted CanIt, a fully outsourced anti-spam solution.
