InvisiMail Deluxe is perfect protection and security for home or small business users against the dangers posed by Internet email. InvisiMail automatically encrypts and decrypts your e-mail with worldwide strong (607-1279bit) encryption. The entire process is transparent and performed in the background. You do not need to know anything about encryption to use it. InvisiMail Deluxe adds effective Anti Spam features which allows the identification, quarantine or banning of Spam mail and advanced "Recursive" Anti viral scanning of emails, which is able to look within email messages and compressed archive attachments such as ZipTM files to identify possible virus threats before they infect your system. InvisiMail's award winning design is the simplest, easiest to use email encryption solution available anywhere. Installation is automatic and InvisiMail supports more email clients (Netscape, Outlook, Eurdora, etc) than any other security solution available. InvisiMail automatically authenticates who is sending you e-mail and checks to determine whether anyone tampered with the e-mail while in transmission. Attached to each message is a Message Signature file that tells you if everything is OK or what went wrong. After Installation you will have two special encryption keys. One is your Public key, which is automatically sent to other InvisiMail users. The other is your Private key that allows you, and only you, to decrypt messages from other users. Messages sent to non-InvisiMail users are sent as plain e-mails without encryption.
