Abstract

A system and method for providing e-mail messages to a user in a more efficient manner. Specifically, the system and method of the present invention enable attachments to be downloaded separately from the text-part of the e-mail message, which requires less bandwidth to download. Instead, these attachments are represented by links in the message which is downloaded to the e-mail client of the user, such that the user can “click on” or otherwise select a link in order to retrieve the attachment. Preferably, the attachment is downloaded to the computational device of the user in a streamed manner.

Claims

1. A method for selectively delivering to a recipient'"'"'s e-mail client via an e-mail proxy a multi-part e-mail message sent to an e-mail server by a sender and stored at the e-mail server, the multi-part e-mail message having at least one attachment containing attachment content attached to the multi-part e-mail message, the method comprising:

acquiring preferences provided by the recipient and stored at the e-mail proxy;

forming an association between the e-mail proxy and the e-mail server;

once said association is formed, retrieving at least one part of the multi-part email message from the e-mail server and storing said at least one part at the e-mail proxy;

sending said formatted message to the e-mail client.

2. The method of claim 1, wherein the multi-part e-mail message includes a message text-part, and wherein said preparing said formatted message includes adding said message text-part to said formatted message.

3. The method of claim 1, further comprising accepting a selection of said link identifier by the recipient from said formatted message and responsively delivering the at least one attachment content from the e-mail proxy to the e-mail client in a streamed format for viewing by the recipient.

4. The method of claim 3, wherein the at least one attachment content is decoded before being delivered.

5. An e-mail proxy apparatus for selectively delivering to a recipient'"'"'s e-mail client a multi-part e-mail message sent to an e-mail server by a sender and stored at the e-mail server, the multi-part e-mail message having at least one attachment containing attachment content attached to the multi-part e-mail message, comprising:

means for acquiring preferences provided by the recipient and stored at the e-mail proxy;

means for forming an association between the e-mail proxy and the e-mail server;

means for retrieving at least one part of the multi-part e-mail message from the email server after said association is formed between the e-mail proxy and the e-mail server and storing said at least one part at the e-mail proxy;

means for downloading the at least one attachment from the e-mail server to the email proxy and saving attachment content under an associated link identifier at the e-mail proxy;

means for retrieving at the e-mail proxy said at least one part of the multi-part email message to be delivered to the e-mail client by the e-mail proxy in accordance with said acquired preferences;

means for preparing a formatted message at the e-mail proxy for delivery to the email client, said formatted message containing said at least one part of the multi-part e-mail message and said associated link identifier, such that the at least one attachment content is not delivered to the e-mail client with the formatted message; and

means for sending said formatted message to the e-mail client.

6. The e-mail proxy apparatus of claim 5 further comprising:

means for accepting a selection of said link identifier by the recipient from said formatted message; and

means for responsively delivering the at least one attachment content from the email proxy to the e-mail client in a streamed format for viewing by the recipient.

7. The e-mail proxy apparatus of claim 5, wherein the multi-part email message includes a message text-part, and wherein said means for preparing said formatted message further comprises means for adding said message text-part to said formatted message.

8. The e-mail proxy apparatus of claim 5 further comprising means for decoding the at least one attachment content before being delivered.

9. A method for selectively delivering to a recipient'"'"'s e-mail client via an e-mail proxy a multi-part e-mail message sent to an e-mail server by a sender and stored at the e-mail server, the multi-part e-mail message having at least one attachment containing attachment content attached to the multi-part e-mail message, the method comprising:

acquiring preferences provided by the recipient and stored at the e-mail proxy;

forming an association between the e-mail proxy and the e-mail server;

once said association is formed, retrieving at least one part of the multi-part email message from the e-mail server and storing said at least one part at the e-mail proxy;

downloading information relating to the at least one attachment from the e-mail server to the e-mail proxy, whereby a link identifier is established for the at least one attachment content;

retrieving at the e-mail proxy said at least one part of the multi-part e-mail message to be delivered to the e-mail client by the e-mail proxy in accordance with said acquired preferences;

preparing a formatted message at the e-mail proxy for delivery to the e-mail client, said formatted message containing said at least one part of the multi-part e-mail message and said associated link identifier, such that the at least one attachment content is not delivered to the e-mail client with the formatted message; and

sending said formatted message to the e-mail client.
