Roaring Penguin Software stops spam in outgoing e-mail with its improved
outbound rate limiting feature for Universities, Web Hosts, ISPs and
OTTAWA, Feb. 17 /CNW/ - Roaring Penguin Software Inc. increases the
effectiveness of its "Outbound Rate Limiting" feature by allowing rate
limiting based upon the sending IP Address. This is in addition to
rate limiting outbound mail based upon the sender's e-mail address.
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 e-mail administrator.
This new outbound spam filtering feature allows ISPs to quickly detect
and block compromised customer machines that send spam while varying
the sender address.
CanIt's IP-based rate-limiting even works for hosts that relay through a
central mail server forwarding mail out through the CanIt server.
CanIt can pick out the real client IP addresses from the stream of outgoing e-mail and block only the offenders while allowing unrelated machines to
continue to relay. As with all other CanIt features, the IP-based
rate-limiting feature is IPv6-capable.
