Spam. How to fight it.

Spam. How to fight it.
Internet is flooded today with undesirable advertising letters also known as spam. Both for an ordinary user connecting to Internet via dialup and for various companies paying for the dedicated line or using DSL spam equals wasted megabytes of information. The megabytes, which are paid for. And time, wasted on viewing advertising offers of unnecessary things or services.
Currently there are a lot of ways to guard your email box against unceasing attacks of “Viagra”, tourist reservations, commercial seminars and the best “windows and doors” in the world, which can be bought cheaply and simply. One of the cures could be changing the email account. But this is by no means a panacea: in a while the new box will be displaying nonsense newsletters from all over the world. You can of course use the server-inbuilt filters or paid resources which try to minimize the spam flow, letting through just the letters from “authorized addressers”. But the server filters block just a small part of proposals to “enlarge” or “relax”. And the powerful “authorization” protection is, first, expensive (plus a monthly fee), and second, is very inconvenient for people on the contact-list (they have to undergo a lengthy “authorization” procedure).

Ideal filter
To clean the mail account from spam a universal anti-advertising shield is needed which will save the money otherwise wasted on downloading weighty letters traffic and the time otherwise lost on viewing and deleting them. Such a shield is the programs which remotely check the mail in the user box without uploading them and block unwanted letters immediately at the server. Such programs are many. They differ in interface and functionality, but have one thing in common: obligatory check of email at the server. Without this feature there would be no sense in the blockers at all. To upload messages and check them locally is not a big deal. The applications differ in their settings, spam filtering ways, speed of work and different features enabling maximum efficiency. The most wide-spread way of blocking spam is by letter headings and continuously updated list of “illegitimate” addresses, which are known as harmful advertisements distributors.
What should an ideal spam blocking application be like? First, it should cope with its primary duties flawlessly. Second, it should have a nice interface, be simple to tune and work autonomously. Third, it shouldn’t prevent normal functioning of other programs, mail clients in particular. Let’s look into the interior side of a spam-blocking application and decipher the underlying basics.

Spam-blocking principles
Usually the application downloads message headers which undergo “partial enquiry”. Depending on the functionality of a certain “tool”, filtering is conducted by fields (header, sender, addressee etc.), black and white lists of electronic addresses in the database and a wider list of recognized spam generating servers. For checking lists are used, either created by developers or edited by users. Undoubtedly, the more thorough the home-made spam-blocking provisions, the better, but ideal work cannot be achieved without proper tuning of blocking and filtering rules. Of course a user setting the most rigid rules risks losing with the blocked spam useful and harmless letters. But in any case, it’s a private decision.
Apart from preinstalled blocking rules, user can make his/her own corrections, such as widening the “dangerous server” lists, editing black and white lists and creating his/her own lists conforming to certain rules (for instance, taking into account letter size plus filtering from “that particular left-most Korean server list). On installing the application and adjusting its settings (or you can leave everything as it is) and initial workability check, one can make a final decision concerning fitness of the filter for further use. It remains to decide which application to select.
