| 20090271489 | ELECTRONIC MAIL SYSTEM AND METHOD - An electronic mail server processes large numbers of electronic messages. The server includes software which detects various status conditions relating to each message. One or more user-defined software modules are attached to the server software, such that upon detection of a given condition, the associated module is executed. Thus, the modules are executed in real time, i.e. while the main server software is operating. In one example, the user-defined modules can be used to update a database of addresses in real time, when messages to certain addresses in the database are returned as undeliverable. | 10-29-2009 |
