Abstract

An Internet mail bridge is provided for downloading e-mail messages from Internet mail servers supporting different email protocols, such as the Post Office Protocol 3 (POP3) and Web Distributed Authoring and Versioning (Web DAV) protocol, and delivering the downloaded messages, which are in different formats, to a mail server on a local area network. The Internet mail bridge has a mail manager that is independent from particular e-mail protocols or e-mail formats. For each e-mail account, the mail manager instantiates a mail connector object that contains logic for downloading e-mail according to the e-mail access protocol of that account, and invokes the mail connector object to download e-mail messages from that account. The mail manager then instantiates and invokes mail deliverer objects tailored for handling different message formats to deliver the downloaded messages to the local mail server.

Claims

1. A system comprising:

at least one processor; and

memory encoding computer executable instructions that, when executed by the at least one processor, perform a method of retrieving messages from a first account and a second account, the method comprising;

retrieving a first message from the first account supporting a first protocol, wherein the first message is retrieved by invoking a first method having logic for retrieving the first message according to the first protocol;

retrieving a second message from the second account supporting a second protocol, wherein the second protocol is different from the first protocol, and wherein the second message is retrieved by invoking a second method having logic for retrieving the second message according to the second protocol, wherein the second method is different from the first method; and

storing the first and second messages locally.

2. The system of claim 1, wherein the method further comprises:

sending the first and second messages to a local server.

3. The system of claim 2, wherein sending the first and second messages to a local mail server comprises:

invoking a third method having a first format-specific logic for delivering the first message to the local server; and

invoking a fourth method having a second format-specific logic for delivering the second message to the local server.

4. The system of claim 3, wherein the third and fourth methods are invoked by a mail delivery manager.

5. The system of claim 1, wherein the first and second methods are invoked according to a schedule.

6. The system of claim 1, wherein the first and second methods are invoked by a mail download manager.

7. The system of claim 1, wherein the first and second methods are invoked as separate threads.

8. The system of claim 1, wherein storing the first and second messages locally comprises placing the first and second messages in a local mail queue.

9. The system of claim 1, wherein the first protocol is the Post-Office-Protocol Version 3 (POP3) protocol.

10. The system of claim 9, wherein the second protocol is the Web Distribution and Authoring Versioning (Web DAV) protocol.

11. A method of retrieving messages from a first account and a second account, the method comprising:

retrieving a first message from the first account supporting a first protocol, wherein the first message is retrieved by invoking a first method having logic for retrieving the first message according to the first protocol;

retrieving a second message from the second account supporting a second protocol, wherein the second protocol is different from the first protocol, and wherein the second message is retrieved by invoking a second method having logic for retrieving the second message according to the second protocol, wherein the second method is different from the first method; and

storing the first and second messages locally.

12. The system of claim 11, wherein the method further comprises sending the first and second messages to a local server.

13. The method of claim 12, wherein sending the first and second messages to a local mail server comprises:

invoking a third method having a first format-specific logic for delivering the first message to the local server; and

invoking a fourth method having a second format-specific logic for delivering the second message to the local server.

14. The method of claim 13, wherein the third and fourth methods are invoked by a mail delivery manager.

15. The method of claim 11, wherein the first and second methods are invoked according to a schedule.

16. The method of claim 11, wherein the first protocol is the Post-Office-Protocol Version 3 (POP3) protocol.

17. The method of claim 11, wherein the first method does not have logic for retrieving messages according to the second protocol, and wherein the second method does not have logic for retrieving messages according to the first protocol.

18. A computer storage medium encoding computer executable instructions that, when executed by at least one processor, perform a method comprising:

retrieving a first message from the first account supporting a first protocol, wherein the first message is retrieved by invoking a first method having logic for retrieving the first message according to the first protocol;

retrieving a second message from the second account supporting a second protocol, wherein the second protocol is different from the first protocol, and wherein the second message is retrieved by invoking a second method having logic for retrieving the second message according to the second protocol wherein the second method is different from the first method; and

storing the first and second messages locally.

19. The computer storage medium of claim 18, wherein the method further comprises sending the first and second messages to a local server.

20. The computer storage medium of claim 19, wherein sending the first and second messages to a local mail server comprises:

invoking a third method having a first format-specific logic for delivering the first message to the local server; and

invoking a fourth method having a second format-specific logic for delivering the second message to the local server.
