A spam filter gateway should have the ability to decipher wanted and unwanted contacts, learn from user classifications, host suspicious files, and block certain senders. It should also quarantine messages and have the technology to learn from the user. A powerful spam filter gateway allows for custom definitions and rules and hosts all incoming messages to protect against viruses and malware.
A spam filter gateway is often the only thing standing between a computer user and millions of unwanted solicitations. There are several key options any spam filter gateway should contain to prevent these nuisances, and unfortunately, most programs found on the Internet lack enough tools to adequately protect the user. The number one feature a spam filter gateway should contain is the option to decipher wanted and unwanted contacts, but it should also have the ability to learn from user classifications within each category. An online server to host these suspicious files is also a great attribute, as is the ability to block certain senders permanently.
When a prompt appears on a user’s computer screen or within their email account, the basic job of a spam filter gateway is to quarantine that message so it can’t harm the computer. Since there are billions of places a message can originate from on the web, it would be nearly impossible for a single program to be able to effectively categorize them all. For example, a user may encourage sales solicitations on his favorite websites where others would consider him spam, so a spam filter gateway must have the technology to learn from the user and sort these messages accordingly.
Many users are simply looking for a spam filter gateway to separate the important emails from the junk mail they receive. Most programs of this type will include this capability, but some of them allow for additional classifications as well. For example, a user may not want images or videos sent to their mailbox due to the associated download time, but some spam filter gateway programs will order these types of matches between approved and blocked senders. While both types would be blocked by the user’s computer system, those from trusted sources would be stored on a server for future viewing. A powerful spam filter gateway allows for the implementation of hundreds of custom definitions and rules.
Viruses and malware are commonly hidden on the Internet, so another feature of a solid spam filter gateway would be to host all incoming messages somewhere other than the user’s computer. The importance of this trait is simple; if the solicitation is seen in cyberspace, it poses a much lesser threat. Many viruses are programmed to run immediately when opened, and this extra layer of protection usually allows a virus scanner sufficient time to locate and neutralize the threat. A great spam filter gateway will remember these types of instances and never allow correspondence from that sender again.
