Anti-Spam Protection
Spam, UBE or abusive email is estimated to be 90 billion messages per day, accounting for more than 70% of all email traffic. Research firm The Radicati Group forecasts the spam percentage to increase to 82% by 2011 despite all efforts. It's estimated that spam accounts for about two-thirds of corporate e-mail traffic. Phishing has rapidly grown its share to nearly 80% of all email-borne threats, greatly exceeding executable malware such as viruses. The result is wasted worker time and extra work for technical staff.
Now is the time to take control.
This processing flowchart shows some of the sophistication behind anti-spam internal logic. Our modular design allows fast adoption to new spamming methods.

Comprehensive Technology
IceWarp's Anti-Spam system is a complete solution approaching 100% accuracy. It is a highly developed subsystem that evolves, practically on a daily basis. The engine is improved to handle the latest spammer tricks. New rules, spam signatures and engine changes are downloaded and installed transparently through AutoUpdate technology, in response to the ever-changing spamming tactics.
- 97% accuracy on average
- Low false positives rate
- 20+ technologies: SpamAssassin, Bayesian, RBL, URIBL/SURBL...rDNS, auto-whitelist
- AutoUpdates
- Multiple spam management scenarios
- Manual, semi-automatic, user-driven processing
- Multiple spam actions: reject, delete, quarantine, tag, sort
- User/domain/ system level white listing & bypass control
Quarantine
To reduce the false positives rate without decreasing Anti-Spam efficiency, email from unknown senders which cannot be clearly deemed spam or ham can be quarantined. Manual spam processing means that the end user can inspect a quarantine report sent on a daily basis and whitelist senders of messages accidentaly tagged as spam. Semi-automatic processing can be achieved by deploying Challenge Response- senders of quarantined messages will need to authorize themselves by completing C/R confirmation.
- Scheduled quarantine reports by email to each user
- Details shown include Subject, From, Date/Time
- Works with any HTML capable email client
- Not message but sender based
- Actions/Voting links to Authorize sender, Delete or one-time Deliver messages
- Users can manage and inspect Quarantine fodler from WebMail
- Semi-automatic management with Challenge Response option
- Messages left in quarantine are deleted on schedule
- Authorized senders won't be tagged/challenged ever again
Auto Whitelisting
Modern anti-spam systems need to be aggresive in catching spam. To prefent false positives, our system employees automatic whitelist learning to support these comprehensive approaches without the fear of losing important messages. Closed working groups can achieve 100% spam-free email without much effort. Messages from your business contacts and people you've been in touch with will never be tagged as spam.
- Addresses emailed to by any user
- Senders authorized by Challenge Response
- Quarantine senders authorized by user/admin
- WebMail Address Book and shared Outlook contacts
- Jabber IDs from Instant Messaging client roaster
- Senders of email moved to Whitelist Filter folder in WebMail
- Senders of email sent to special whitelist learn-rule address
Email from whitelisted addresses will be delivered straight to user's mailbox, completely bypassing anti-spam processing.
