Abstract: The invention provides a system and method for determining when a message is received by a recipient or an agent for the recipient. A link is activated at the recipient to provide an indication that the message has been opened by the recipient. The activation of the link may cause a server remote from the recipient to take some further action.

Abstract: A server transmits a message from a sender to a recipient. The server receives from the recipient an attachment relating to the message route between the server and the recipient. The server transmits to the sender the message and the attachment and their encrypted digital fingerprints and expunges the transmitted information. To subsequently authenticate the message and the attachment, the sender transmits to the server what the server has previously transmitted to the sender. The server then prepares a digital fingerprint of the message and decrypts the encrypted digital fingerprint of the message and compares these digital fingerprints. to authenticate the message. The server performs the same routine with the attachment and the encrypted digital fingerprint of the attachment to authenticate the attachment the recipient replies to the sender's message through the server. The server records proof of the delivery and content of the reply to the sender and the recipient.

Abstract: A sever receives data from a sender to be dispatched to a recipient. Before dispatching the data to the recipient the server sends a message to the sender's email address requesting a response which will confirm the sender's authorship of the data. Upon receiving the confirmation about sender's authorship of the data, the server transmits the data together with an identification of the sender to the recipient.

Abstract: A server transmits a message and attachments from a sender to a recipient. A hash is provided of (a) the message, (b) an identification of the sender and (c) a hash of the attachments to form a data string. Instructions may be included for the recipient to send a hashed encryption of the string to a website at the server by registered electronic mail which provides options to obtain other electronic advantages. To authenticate the message, the recipient transmits the message, the attachments and the hashed encryption of the string to the server website. The server decrypts and detaches the hashed encryption of the string to provide a first string and hashes the message, the sender identification and the hashed attachments in the first string to form a second string. The server also detaches and hashes the attachments from the message received at the server website to form first hashed attachments and detaches the hashed attachments from the string to form second hashed attachments.

Abstract: A system and method providing for appending of a note or instruction to the contents of an email such that the note or instructions is only appended to emails of selected recipients of a group of recipients, with only the email going to the other recipients of the group of recipients is provided.

Abstract: A server receives a message from a sender and adds a link to the message, and then transmits the message with the link to a recipient. The server receives from the recipient a manually initiated response and generates an indication of receiving the response from the recipient and transmits the indication to the sender. The sender may also authenticate the message, and may record proof of the delivery and content of the reply to the sender and the recipient.

Abstract: A server transmits a message from a sender to a destination address. During transmission, the server and the destination address have a dialog constituting an attachment, via a particular one of SMTP and ESMTP protocols, concerning the message, the server and the destination address. The message passes through servers between the server and the destination address. This passage is included in the attachment. Verifiers are provided for the message and for the attachments. The verifiers may constitute encrypted hashes of the message and of the attachment. The sender receives the message, the attachments and the verifications from the server before authentication and transmits the message, the attachments and the verifiers to the server to obtain authentication by the server. The server operates on the message and the message verifier to authenticate the message and operates on the attachments and the attachments' verifier to verify the attachments.

Abstract: Third party verification of the content and delivery of an electronic message such as an e-snail, is provided using a server that receives an e-mail sent or forwarded to a specified addressee, and “tags” the message to indicate that it is “registered” with the service provider. The server establishes a direct connection with the addressee's Mail User Agent (MUA), and transmits the tagged email to the addressee's MUA, as well as to the MUA's of any other addressees. After receiving responses from the receiving MUA's that the message was successfully received, the server creates and forwards an electronic receipt to the message originator. The system operators can provide independent third party verification that the receipt is a genuine product of their system and that the information pertaining to content and delivery of the message is accurate, without the need to archive either the original message or the receipt.
