A perfect anti-spam program would be a program that deletes absolutely every email you shouldn’t, and wouldn’t want to receive. But it is never going to be possible. People who create and send spam emails are always of the creative sort, and continue to find new ways and strategies to override spam filters, while anti-spam software developers work overtime to beat the spammers in their new game.

Most anti-spam programs can be customized to your needs, and only the approved emails come into your inbox. Let’s look at the features and benefits of anti-spam software.

Deleting spam before it reaches the inbox. There are spam filtering programs that would actually read the messages and not just consider the email address when filtering out unwanted emails. You can also get spam filtering programs that would allow you to tag emails with certain attachments as spam. A sign of a competent anti-spam program would be the ability to delete spam emails before your inbox receives one of them.

There should be regular updates for the filters. There are many spam filter types to be found on your average anti-spam software. Every few weeks or months or so, these spam filters would be replaced with newer, more updated versions. You can be sure that your anti-spam program is current this way.

It’s also good to be able to customize your spam filters. The best anti-spam software makes it a point to make spam filters adjustable, allowing you to customize based on the types of emails you should receive and should not receive.

Quarantining your spam emails is another necessary feature. Spam blockers prevent junk emails from entering your inbox and move them to a specific quarantine or trash folder. Quarantined emails are stored there for a number of days and then deleted forever. This delay allows you review deleted emails to check if all of them are spam.

Relating to the above requirement, legitimate emails mistaken as spam should have a recovery option. Naturally, you would need to send the mistaken spam emails back to your inbox once proven legitimate.

You’ve heard of the blacklist – you should have that, and a whitelist. You can maintain your own lists of trusted email senders (whitelist) and suspicious email addresses, from which you are used to receive spam (blacklist). This can be updated at any time.

You should have the capacity to watch more than just one email account. This would let you have your spam filter program guard more than just one email account. Both home and work email addresses should be covered, at least.

Automatic mode. Certain anti-spam programs can check inbound mail at fixed time intervals and delete spam without your participation.
