Spam filter is a program designed to protect the user from spam and it is used to filter incoming email or links.
The spam filter uses ready-made lists with undesired addressees or website addresses. Accordingly, these lists must be created. To make the spam filter work more efficient, it must be "trained". During the "training", the spam filter specifies the criteria by which the letters will be sent to spam. It is also necessary to mark "non-spam" letters so that the filter can catch the difference between personal messages and spam. Often, while producing mass mailings of your emails, you unwillingly become a spammer. This is because you do not follow the rules of mailing.
