There are several threats for computer security come every now and then but one that remains a constant nuisance is spam. This particularly applies to internet marketers who are constantly at risk of accessing malicious content. Spam is annoying, but sometimes it can be dangerous too. Sure, these e-mails might interrupt your busy schedule, but spam can also be dangerous. The most serious things about spam is sometimes they could unleash a nasty virus on your network that could be crippling to your computer and server machines.
Anti-spam services and experts tend to peg spam anywhere rate from 50 to 90 percent, depending on the services they offer. You can also try spam filtering by Everycloud Tech for even better spam filtering. Anti-spam applications simply act as a filter and identify spam programs/emails through different techniques and prevent them from reaching your inbox.
These filtrations are based on different processes, automatically checking each message to determine just how much of a chance that it might be spam. There are few other programs that try to block all email that contains advertisement of any kind… these techniques are not always helpful because not all the advertisement mails are spam. Some of them may be something you’re actually interested in.
While choosing an appropriate anti-spam services, make sure they aren’t simply trying to block all emails that relate or don’t relate to a particular topic. These types of programs will almost always identify some emails as spam that aren’t really spam, because it’s simply not smart enough to understand the meaning and variations of every word out there.
Here are few of the options that will probably server you better…
These filters try to stop spam by categorizing the senders as trusted users or spammers and allowing or blocking their messages accordingly.
This is one of the popular spam-filtering method that works by completely stopping any email that’s sent from someone on the list. The main task of blacklist is to record the IP (Internet protocol) address or email address that are previously used for sending the spam. When any incoming message arrives from a sender on that list, before sending it to your inbox the filters check the email address or IP, and if it’s on the blacklist, it ain’t going anywhere except your spam box.
Real-time blackhole list
This method works identically to blacklist but this filtration technique requires less maintenance. This is because most of the real-time blackhole lists are usually maintained by the third parties, who build comprehensive blacklists time to time on a subscriber’s behalf. All you have to do is connect with them when checking your mail and it will automatically check the senders IP and block if sender is on the list.
This technique is opposite to blacklist process. In this, instead of letting you block email from specific senders. it allows you to create a list of senders who are allowed to send emails. Any email you receive that comes from someone not on this list will be sent to your spam box. This is among the most trusted ways of filtering the emails. But keep in mind, that any sender other than someone on the trusted list will be mark as spam so you need to create the list very carefully.
This is a fairly new spam-filtering technique. It’s based on the fact that many spammers will only send a spam message once. If you receive an email that the filter believes is spam it will send it to the spam box and send a reply to the sender saying the message failed to go through. Obviously, if it wasn’t someone trying to spam and they needed to really get an email to you, they’ll probably try again. If that happens, the filter will let the second message through.
Instead of enforcing across-the-board policies for mails from specific IP or email address, content-based filters examine the phrases or words in individual message and categorize them accordingly either they are spam or not.
This is the simplest kind of filtration and quite much similar to content based filter. These filters generally block such e-mails that contain several words from a spam list that you or a program has created.
As you can see, there are many ways to block spam. Some will be more effective in certain situations than others, though. So, as with every decision you make about your business, it’s one that only you know what will work best for you.
