Abstract

The invention relates to a method and system for handling E-mail messages in a communication system. According to the present invention in a communication system comprising one or several intermediate receivers any attachment in an E-mail message is detached in the intermediate receiver and stored. Furthermore the attachment is replaced with a reference to the stored attachment before the E-mail message is forwarded to the recipient. With the use of the present invention the attachment of the E-mail stays always as close as possible to the receiver location. Changes to E-mail handling components on the sender'"'"'s side and in the transmitting network are not necessary. Since storage and transmission of redundant data is suppressed, there are considerable savings of transmission cost, disk space, and mailing time.

Claims

1. Method for handling E-mail messages in a communication system comprising one or several intermediate receivers (102), each serving at least one recipient, the method comprising:

detaching, in the intermediate receiver (102), any attachment (300) in an E-mail message and storing the attachment, replacing each attachment in the E-mail message (10) with a reference (400) to the stored attachment, and

forwarding the E-mail message (10) with the reference (400) from the intermediate receiver (102) to the recipient specified in the E-mail message (10).

2. The method of

claim 1

, wherein the detaching comprises:

copying the at least one attachment (300) to an attachment database (105) accessible to all intermediate receivers (102) at a receiving side (100).

3. The method of

claim 1

, further comprising:

defining access conditions such that the stored attachment (300) is accessable for each recipient of the according reference (400).

4. The method of

claim 1

, wherein the attachment is replaced with multiple references to multiple versions of the attachment.

5. The method of

claim 1

, further comprising:

upon an according request of the recipient, transferring the stored attachment to the recipient.

14. Computer program product directly loadable into the internal memory of a computer, comprising software code portions for performing the steps of

claim 1

when said product is run on a computer.

15. Computer system comprising an internal memory, wherein the computer program product of

claim 14

is loaded, and an execution environment for executing a method of handling E-mail messages in a communication system comprising one or several intermediate receivers (102), each serving at least one recipient, the method comprising:

detaching, in the intermediate receiver (102), any attachment (300) in an E-mail message and storing the attachment,

replacing each attachment in the E-mail message (10) with a reference (400) to the stored attachment, and

forwarding the E-mail message (10) with the reference (400) from the intermediate receiver (102) to the recipient specified in the E-mail message (10).

6. System for handling E-mail messages in a communication system, comprising one or more intermediate receivers (102), each serving at least one recipient, the intermediate receiver (102) comprising an attachment handling device (104) adapted for

detaching any attachment (300) in an E-mail message (10) and storing the attachment (300),

replacing each attachment (300) in the E-mail message (10) with a reference (400) to the stored attachment, and

forwarding the E-mail message (10) with the reference (400) from the intermediate receiver (102) to the recipient specified in the E-mail message (10).

7. The system of

claim 6

, further comprising a first attachment database (105) accessable to all intermediate receivers (102) at a receiving side (100) and connectable to the attachment handling device (104).

8. The system of

claim 7

, wherein the first attachment database (105) is located at the intermediate receiver (102).

9. The system of

claim 7

, further comprising for at least one of the recipients an attachment copy device (111) adapted for transferring the stored attachment from the first attachment database (105) to the recipient.

10. The system of

claim 7

, further comprising a second attachment database (112) connectable to the attachment copy device (111).

11. The system of

claim 6

, wherein the intermediate receiver (102) is a server in a client-server architecture, serving at least one recipient'"'"'s client (110).

12. The system of

claim 10

, wherein the second attachment database (112) is located at the recipient'"'"'s client (110).

13. The system of

claim 11

, wherein the second attachment database (112) is located at the recipient'"'"'s client (110).
