Users running their own mail Linux server (either exclusively or as part of a wider hosting package) can employ the services of the Box Trapper application.
Used in conjunction with a dedicated spam tool or security software on your PC, this can be a superb way to prevent spam from being received in your mail client.
Box Trapper works by configuring a set of hard and fast rules, based on the sender name, domain, addressee and subject. Blocked senders are added to a “blacklist” – approved senders go into a “whitelist”.
While similar settings can be found in email clients, PC resources are put to work by sorting through email messages. If you have the opportunity to save your PC some unnecessary work, take advantage of Box Trapper.
