Communications system providing message aggregation features and related methods

A method of operating an aggregation server comprising a processor for aggregating electronic mail (e-mail) messages comprising:

• executing an aggregation module with the processor for periodically aggregating e-mail messages stored on a plurality of source message servers to a target message box;
• the aggregation module increasing a period of sending messages to the target message box based at least one e-mail of delivery failure, and thereafter decreasing the period of sending messages to the target message box based upon at least one successful delivery e-mail;
• the aggregation module selectively re-sending e-mail messages;
• and
• executing an intelligent checker module with the processor for aggregating the e-mail messages from the source servers to said target message box.

A physical computer-readable storage medium having computer-executable modules to be executed by an aggregation server, the computer-executable modules comprising:

• an aggregation module for periodically aggregating electronic mail (e-mail) messages stored on a plurality of source message servers to a target message box;
• and
• said aggregation module increasing a period of sending e-mail messages to the target message box based upon at least one e-mail delivery failure, and thereafter decreasing the period of sending e-mail messages to the target message box based upon a successful e-mail delivery;
• said aggregation module selectively re-sending e-mail messages for which delivery failure messages are received;
• an intelligent checker module for aggregating the e-mail messages from the source servers to the target message box.
