OTTAWA, Feb. 4 /CNW/ - Roaring Penguin Software's CanIt Reputation List
collects IP reputation data on e-mail servers from a worldwide network
of sensors. Roaring Penguin currently aggregates this data into four
DNS-based block lists:
Spam Source: A list of IP addresses that have sent mostly spam and very little
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.
To these block lists Roaring Penguin has added a new list called "Mixed" for hosts that send a mixture of spam and non-spam.
Roaring Penguin found that the old "SpamSource" list would often list outbound mail servers for large e-mail
providers. These servers tend to send a lot of spam, but they also
send a lot of non-spam e-mail.
The change to Roaring Penguin's Reputation Lists means that about 5600
machines formerly listed on the "SpamSource" list are now listed on
"Mixed". This still leaves almost 1.9 million machines listed on the
"SpamSource" e-mail reputation list.
CanIt 8.0 is available as:
CanIt-PRO, an anti-spam / anti-virus appliance or a soft appliance.
CanIt-Domain-PRO, spam filtering software that allows service providers
such as MSPs to host anti-spam for their customers.
Hosted CanIt, a fully outsourced anti-spam solution.
