Inbox100 keeps your inbox 100% clear of spam ? from the moment it is installed. Only e-mails from your approved list are permitted into your inbox. This approved list is automatically developed from your Address Book and Sent Items folder on installation. All e-mails from other senders are quarantined. E-mails in your quarantine folder are ranked according to the spam probability rating making Inbox100 the software that is quick and easy to identify legitimate mail. The ranking is based on Bayesian scoring and learns from both every spam and legitimate e-mail. Inbox100 has customizable settings allowing auto-deletion of spam mail, plus the optional addition of approved senders from other e-mail folders. Inbox100 also automatically deactivates Web beacons inserted into spam mail ? ensuring the user can safely view mail without confirming their e-mail address to spammers. Inbox100 also protects your approved list from virus attack. Works with POP3 and Exchange Mail accounts.
