Spam
Spam is about unwanted e-mails or junk mail. Nowadays, spam mails literally flood the e-mail inboxes of users. A spam filter provides a remedy against unwanted spam mails. Most e-mail providers have a practical function for reporting spam e-mails. It teaches the e-mail client to recognize these spam mails and to not let them through in the first place. In public forums, chat rooms, etc., everywhere where contact information can be publicly stored, the main e-mail address should never be used, but only a substitute e-mail address. In addition, never respond to spam e-mails and do not download any attachments in spam e-mails.
