curiously the word spam has a very different origin from what many of us might think. And it is that this name comes from a brand of canned meat, which American soldiers received from their relatives during World War II.
But today in computing it has acquired a different name; it is known as an unsolicited message which generally refers to the sale of products and services without authorization. So it is usual that notifications are received that are not of personal interest.
Previously, these were only targeted or better said, known in emails, but this has expanded to other platforms such as blogging, instant messaging, social networks and even mobile devices. So that you learn more about it, in the next tutorial we will explain you step by step What is it? How can spam filters help you? and more.
What is SPAM or junk email from my inbox?
As we previously indicated, its name comes from an old brand of canned meat. Even though, it currently has a very different definition and is spam. Referring to unsolicited or desired messages. Mainly of an advertising type or those that are sent in bulk.
In the spam category too you have to add the messages that are sent for fraudulent or malicious e-mails. Generally, these contain false information to carry out scams, so they have the sole objective of obtaining the recipient’s personal data.
But, this type of mail Today it is not only limited to email, since social networks or instant messages such as WhatsApp are also affected. Reason why we must be very attentive to what we receive on many occasions.
What is an AntiSPAM and what is this type of program for?
When we talk about antispams programs, whether for computers or mobile devices, we are talking about These allow their users to eliminate or block all that email that they consider unwanted, or that the person has marked the same way.
What can they be used for? Simple, they serve to keep your email inbox, your WhatsApp, Facebook Messenger, Twitters or other applications that you use to communicate, free from these malicious and annoying ads.
It should be noted that this is not only allowed by programs or applications, can also be configured with email services like: Gmail, Outlook and others, so that they block and send to the deleted messages folder, everything that has been considered as spam.
How does an Anti-SPAM work? Principal functions
They work by scanning all the messages that come to you, where in turn these are qualified around certain characteristics. Depending on the score, the release may or may not be considered spam.
After analyzing those who have entered, these can be: blocked, deleted or sent to the “Spam” folder. When they are marked as “Deleted”, it is not entirely true, since they are sent to the corresponding folder.
No notice of this type, under any circumstances, is it completely removed, because there may be cases where messages that are not spam, are cataloged in this way. So to prevent them from being deleted, they are archived until you review it and you are in charge of canceling or recovering them.
What are the types of Anti SPAM that exist and how are they different?
There are two main types of anti spam, these are:
In addition to this, we can see other varieties of filters, such as:
Bayesian antispam filters
Bayesian filters work primarily with experience, and They are learning from those messages that the users themselves mark as such. So they need other people to be effective and improve. That is, if the user qualifies an email as such, what they will do is compare those marked emails with others and create a database to discard them at once.
This type of filters can raise the alert by means of words or the use of some effects, for example: the word “FREE” is capitalized or the use of bold fonts with colors, bold or with yellow shading.
The lists they use are generated by detecting patterns, starting from the e-mails that were manually marked as spam. So that In some cases, non-junk mail may be marked as spam and appear in the spam tray.
Blacklists exclude any message that comes from certain IPs. These are databases that show addresses where bad actions have been performed, such as mass mailing.
It works by mail servers that check if it is hosted there, in order to know whether to accept or reject the received mail. The problem arises when it cannot differentiate if these are sent voluntarily. So you may find yourself in one of them for no reason.
The reasons can be the following:
- You may have sent a message to a spamtrap or trap mail, these are emails that the email service providers have created and have no activity. They use it as an alarm method, to catch spammers.
- Your email has been hacked and they have sent messages automatically.
- Your computers were infected by a virus that constantly sends emails to anyone.
Firewalls also known as firewalls, they are nothing more than systems in charge of restricting the unauthorized access of certain elements. Those work by rules that are established by the provider and its administrator. They generally use a combination of Bayesian filtering, blacklisting, and others to prevent spam.
So this will make all messages received or sent, go through the firewall that will be in charge of examining each message, and if they do not meet any of the security criteria, they will be blocked.
Challenge / response filters
Although these are not as widely used, there are many that still implement them. It works in the following way; if you send an email with this filter, and still the contact is not on that person’s friends list or notebook, you will be considered a stranger. In such a way that you will be labeled as a spammer.
This to verify that you are or not, what it does is that an automatic response is sent to you with a question to answer or a link that you must enter, to prove that you are not a robot. In case of being labeled as such, it only remains to talk to the recipient to include you on their list.
Anti-spam filters that are based on your reputation
Reputation depends, as it says, on your position, that is, on the scores that the sender’s identification acquires. This filter is based on the sending IP address and the name of your domain used in sending the e-mails. If you do not have a reputation, they will be watching you, as this will measure your actions and that of your followers.
If you get a good reputation, you will get a good percentage from the people who open your campaigns and links in email messages.
Why should you use a spam protector? The dangers of SPAM and how to avoid it
It is important to use an anti spam program or application, because These allow you to keep your e-mail accounts more secure. In such a way, that you can protect your personal information and the status of the equipment.

If not, there are also those that may contain malware intended to steal your information or cause damage to your equipment. Such damages can be solved or in the worst case not. It is common for it to happen for those users who are not very experienced or due to carelessness.
In the same way, save time by not having to check emails of this type, since even those senders who use fraudulent or not very credible accounts can be identified. The best way to avoid this is through any anti spam program.
We suggest that if you do not have them and you receive a suspicious email, never open the document or the link that is attached to it.
