CIPAFilter Helps Block Spam Emails
CIPAFilter’s spam filtering system was designed to provide administrators with a
simplified and more effective approach to combating spam and junk e-mail. It targets
the way spammers operate with some very innovative technology. The result is a
tremendous decrease in required management and a “set-and-forget” product that
takes care of your spam without blocking legitimate mail.
The anti-spam provides the following features and benefits.Virtually eliminates spam
The engine operates using a unique multi-faceted system that focuses on attacking the major operating methods of most spammers, rather than investigating each piece of mail. This method ensures little or no junk mail is delivered to the end user, keeping all your users happy. No management or false positives
CIPAFilter’s anti-spam does not require daily management, logs, quarantines, white-list and black-lists, and other management typically associated with anti-spam products. Instead, rest assured that while much of the spam mail is blocked, you will not have to worry about legitimate e-mails not coming through, therefore eliminating management often found in other systems. Compatible with any mail server
Because CIPAFilter operates as a stand-alone mail relay system, capable of forwarding mail to any SMTP mail server located anywhere, it can be used with any e-mail system.
Phase 1 – Legitimate Mail Server Verification
When the CIPAFilter receives e-mail for the first time, it will run through a series of tests, attempting to verify if the sending mail server is without a doubt a legitimate mail server. Most legitimate mail servers pass this stage, and if they do, any e-mail sent is immediately passed through to the user without delay. However, 90% of spammers tend to fail this stage because they are not using legitimate mail servers and/or methods of sending spam.
Phase 2 – CIPAFilter’s Main Defense Mechanism
This phase is very unique to CIPAFilter, and has been designed based on the initial concept of attacking the operating methods of 90%+ of the spammers. When a message is received for a unique new sender, specific information is recorded to verify the identity
These spammers do not get through this stage, while legitimate mail passes right on through. Essentially, an actual block of spam is never enforced, meaning CIPAFilter does not have to keep track of all the logging of what it has done with all the mail. It simply cleverly uses built-in SMTP technology to very effectively combat most spammers’ methods of sending spam.
Phase 3 – Message Analysis Stage
This final phase uses many traditional methods of identifying spam, customized to CIPAFilter’s advantage and used in combination with the remaining portions of CIPAFilter. This technology is very effective at identifying remaining spam e-mail without over blocking or using quarantines.
Approximately 10% of the spam reaches this phase, and the majority is identified and does not reach the end-user. CIPAFilter calls this stage “Spam Forwarding”, and will forward this spam as tagged mail, either to a separate account, or the administrator may customize based on header information, and either delete and/or forward to each user’s spam box. Although 100% of the content of this should be spam, any potential false positives would be part of this phase, and can easily be located.
CIPAFilter has a built-in white-list that typically is only used rarely if a domain is encountered that for some reason does not pass through either phase. Other logging is available to identify other issues with the e-mail system other than the filtering. It is also safe for users to unsubscribe to any mail they still receive.
Installation
It is very important that the Anti-Spam system is installed properly. Although very simple to setup, it is necessary to have proper forward and reverse DNS entries and ensure there are no firewall rules to the CIPAFilter possibly cause issues.
As always, CIPAFilter can be installed in multiple configuration scenarios. It is recommended to use a Public IP address on the interface used to process e-mail, although it will function behind a NAT firewall with limited possible issues.
