Before I answer the questions on spam filters I'll give a little background on spam. In summary, spam for the miseducated, is an abuse of any form of digital and electronic systems of messaging, leveraging on established communications network to send out UBE or UCE's (unsolicited bulk/commercial emails) that have commercial messages attached to them. Said to have started the moment the internet was released to the public in the early 1990's, spam which first started in email has now spread its viral hands to all forms of digital communication, from instant messaging, newsgroups, search engines, blogs, wiki spams, all forms of cyberspace advertising and forum/discussion groups.
Email spam has been estimated to eat 90% of the daily email traffic in the world today. The figures are daunting because of a few simple reasons, which include the fact that email or any form of digital spamming is extremely easy to do and extremely cheap to set up - the only thing that has to be done is that these advertisers must be able to manage their email and contact lists. Also, while the fight against spam has been on the rise for the past few years, there have been still a few countries who refuse who classify the activity as illegal, which means that the majority of spam distributors either operate within these legal free zones or contract out their spam activities to operators in these countries.
The side effects of spam will always have to be borne by ISP's and network providers. Increased cost, increased volume, fraud, low productivity and all the stigma of having a network filled with spam are the responsibilities of those who have nothing to do with the spamming activities. While there are efforts across the board to include filters and anti-junk programmes within email clients and instant messaging programmes, the efforts have not been enough and normally, it is a technological afterthought - their core business is still communication and the resources that have been put into it is not enough. This is why you need a dedicated spam filter programme, which has teams of tech experts looking into the matter.
If you have ever used an email client with a built in junk folder, you will always come across the problem of either some junk mail getting to your inbox or mails you need to receive going to the junk folder. Don't be confused when it comes to your time, because time is a valuable commodity in this day and age. I would advise anyone to get a spam filter programme because they work far better than jumbled in software. Spam filter programmes are able to read the code within emails, source the point of origin and compare it with patterns using stuff like web crawlers and email web crawlers. This is the sort of protection that anyone needs so that spam ceases to become a bane in their lives. Many are available online and cryo freezer boxes for sale their features can range from the simplistic to the extremely advances. Spam filter programmes work, and getting one is just as important as not missing an email you have been waiting for.
