To manage SPAM emails in the famous Thunderbird mail client, there is the possibility of adding a filter / filters which in combination with the MailScanner application running on IP.GR's servers, allows the email owner to effectively filter out the junk mail they receives.
In brief, MailScanner characterizes emails that it considers to be spam by adding the {SPAM} prefix to the subject of the email.
This mechanism of MailScanner splits spam emails into 3 categories (spam, definitely spam and infected) depending on the content of each email.
Infected emails are cut directly from the Mail Scanner and are not even sent as spam. The remaining emails are stored in the client's mailbox with the corresponding message subject marking (the word {SPAM}).
