Online email services offer blocking filter blocking for your email account.
Many people use Yahoo Mail or another online email service. Many Internet service providers also offer the ability to read e-mail on the Internet. These services usually offer some kind of spam-blocking email filters, similar to those listed in POP mail. Using spam filters is a little confusing, but it helps reduce the amount of spam. We'll look at a couple of common spam filters for online email services.
Yahoo mail
Yahoo Mail has a very simple spam filtering system. In the Yahoo email folder, click the “Settings” link in the top right. From the drop-down list, select "Advanced Options." Select "Spam" on the left sidebar. Spam Guard is the name of an online mail filtering system. Check the box next to the option to enable Spam Guard. Select a frequency to release the spam folder. There is a field for blocking any email address. When you have entered the options you want, click “Save Changes” above the main column. Now click “Back to Mail” at the top of the left sidebar. Spam filtering will be automatic. If you receive a message that you think is spam, you can check the box next to it and send it to the spam folder by clicking the Spam button in the menu bar.
Zimbra Collaboration Suite
Zimbra Collaboration Suite is a program installed on servers of Internet providers for online reading of e-mail. My Internet provider Zimbra is installed as an option for online mail. I can read my mail in a POP email program, such as Outlook, or I can read it on the Internet with Zimbra. When I log into the Zimbra account, I see the main column containing all of my current email, and on the left, the smaller column for the account directory structure. At the top of the search bar is a small menu. Select the "Settings" button. In the settings folder you will see several options at the top. Select the Mail Filter option. You will see a workspace in the center with the Mail Filters heading. Select the "New Filter" button. You now have a pop-up window and the cursor flashes in the field with the filter name. You can call the filter anything. If you are trying to filter out spam associated with weight loss products, you can call it weight loss.
To set up a filter, we need to introduce conditions that will cause the filter to act. The first option is to set a filter for “any” or “total” actions. I chose "everything", as I will be guided by mail, which has a number of characteristics that are repeated often. If you select “any” conditions, you will need to set up a lot of filters, because you are cleaning things too narrowly. One single condition can exist in mail from different sources and can cause many false positives. Suppose I set a filter for “any” condition and use the word “fat” as a string. This filter will act on all emails that include phrases such as “lose weight fast,” “fatty juicy steaks,” and “Johnny's fat lip.” Without adding additional conditions, we cannot combine common hits that are pronounced “Spam”. Our spam emails may include the words “fat”, “diet pills” and “register now”. That is why we require more than one condition to run the filter. By installing a filter with several conditions related to weight loss, we’ll get rid of spam mail, not Aunt Jen, who wants to talk about her “big live bingo jackpot”.
The next step is to select the email document section to set the conditions. The best for spam filtering are subjects from, to, and from the body. "Theme" is important because spammers want to get your attention so that you read the letter. The “body” will contain many common terms that people use to try to sell slimming products. “From” can help, but not often, because spammers often change their addresses and names. “To” is important because spammers insert any name if they are not sure what you have.
In the “conditions” field, select “Subject” and then “Complies exactly” as the Comparison Operator; the second part of the condition. There is a space next to the layouts. Enter the name of the diet pill in this slot; which often appears in your mail. This condition requires that the word in the subject match the term you entered in the space. Now click the plus symbol and you will have another condition to fill. Select a topic again. Select “Match exactly” again, and then type “Quick Weight Loss” in the space. Then you can click the plus sign and add another condition. You can do this several times for words that are often found in the subject line. After clicking the plus symbol again, you can select “Body” on the left side of the condition. You can now enter "Match exactly" as a comparison operator. Then the word that appears in the body.
As you add conditions to this filter, be careful that you build a common combination of terms. By adding some rare words, you will create a filter that will rarely be activated. You should also be careful not to add the words commonly used by your friends. This will result in the loss of a valid email.
There are several different comparison operators that do different things. “Matching exactly / does not match exactly” is a simple operator to understand. The word that we filter must exactly match the term you put in the space. Does not match exactly, it will cause a filter if this term is not found in the letter. Complies It will work exactly if spam always contains the word "pills". If the spammer makes a change in the spelling and uses “Pillz” instead of the condition, it will not work.
The “contain / not contain” operators are a little less strict than the same. If the selected phrase appears somewhere inside the object or body, the filter is triggered. Therefore, the filter for Contains “diet pills” will correspond to: “fantastic pills for losing weight”, “harmful pills for losing weight” and “illegal pills for losing weight”, but not “big diet pill”.
The third set of operators: "Matches a wildcard / does not match the pattern." The wildcard allows you to match the selected word with any string of characters that contains it. In other words, the wildcard character is a placeholder for other letters that you choose to combine with your test word. The asterisk (*) is a wildcard character. We set the filter to start with (*), which is placed at the beginning or at the end of the word of choice. The filter is then started no matter what combination of letters or numbers is added to a specific word. Therefore, using the red diet, the filter will correspond to the “red apple diet”, “red diet pudding” or “red heads not diet”. The wildcard is useful when a spammer combines words with other words. The tactics of merging words in the "Subject" line is a favorite for spammers. You can’t use the “Meets Exactly” tablet when the line is “CheapEffectivePills”. But the condition set for “Matchches Wildcard” * Pills will work with the phrase CheapEffectivePills or AnythingAnythingPills.
At the bottom of the window there is a section for setting the action. Action is what the program does with all the mail that matches the condition you set. Zimbra is not only for spam, so some of the actions are not suitable for working with e-mail. From the drop-down list, select Cancel. Now we are almost done. You can have many other filters configured that will sort or mark mail, and not filter it for spam. All filters in the list will be valid for each email, unless you specify otherwise. You do not want some of the identified spam mail to pass through other filters and also be affected. To prevent other filters from affecting your spam mail, check the box in the lower left corner of this spam filter. In this case, your spam filter will act only on this mail, and not on the remaining filters. Finally click OK at the bottom of the window. You have installed your first spam filter.
Filtration with Zimbra is a complicated process. For effective use, some terms may be required. You may need to use some trial versions and errors before the filter works as planned. If you still receive spam mail, go back and follow the terms again. If you think you are losing a good email, you can return to your filter and set the action “Delivery to folder” and send an email to a folder in your account. Check the folder, and if your valid mail comes back and recycles your filter. Spam operators are constantly changing their tactics, so you must also change the filtering tactics.
Many online email services offer a spam filtering system. Services like Yahoo Mail may not matter to us because we think they throw away email accounts. For many people, their basic email account, which comes with their Internet service provider, is more permanent as well as more important. Internet providers now offer Spam Filters along with their other services. The filters in Zimbra Collaboration Suite are not as strong as in other packages, including software such as SpamAssassin. Zimbra will offer some help in conjunction with filters on your desktop, such as Outlook. More information about Zimbra can be obtained from several sources. The best and fastest way to get help with spam filters is to contact a qualified web designer or IT specialist.
