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

1-34. -34. (canceled)

35. 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 e-mail message from the e-mail server and storing said at least one part at the e-mail proxy;

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

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.

36. The method of claim 35, 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.

37. The method of claim 35, 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.

38. The method of claim 37, wherein the at least one attachment content is decoded before being delivered.

39. 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 e-mail 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 e-mail 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 e-mail 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 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

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

40. The e-mail proxy apparatus of claim 39 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 e-mail proxy to the e-mail client in a streamed format for viewing by the recipient.

41. The e-mail proxy apparatus of claim 39, wherein the multi-part e-mail 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.

42. The e-mail proxy apparatus of claim 39 further comprising means for decoding the at least one attachment content before being delivered.

43. 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 e-mail 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.

44. The method of claim 43 further comprising downloading said at least one attachment from the e-mail server once said association between the e-mail proxy and the e-mail server is formed, and storing said at least one attachment at the e-mail proxy in an association with said link identifier.

45. The method of claim 43, 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.

46. The method of claim 45, further comprising downloading said at least one attachment from the e-mail server after said selection of said link identifier by the recipient is accepted, and storing said at least one attachment at the e-mail proxy in an association with said link identifier.

47. The method of claim 43, 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.

48. A system for selectively downloading a multi-part e-mail message for a recipient, the multi-part e-mail message including an attachment, the system comprising:

(a) an e-mail server that accepts and stores the multi-part e-mail message addressed to a recipient in a storage at the e-mail server;

(b) an e-mail proxy apparatus that acquires and stores preferences provided by the recipient, that forms an association with the e-mail server to retrieve at least one part of the multi-part e-mail message from the e-mail server, to store said at least one part at the e-mail proxy at the e-mail proxy, and to download and store content of the at least one attachment from the e-mail server content under an associated link identifier at the e-mail proxy, that retrieves said at least one part of the multi-part e-mail message for delivery to the e-mail client by the e-mail proxy in accordance with said acquired preferences, and that prepares a formatted message 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
