Email transaction system

The present invention provides a method and a system in which, a determination is made in order to determine whether a destination mail server is able to process a number of emails associated with a distribution list. By requesting performance metrics for each destination server, analysis is performed to understand the processing capacity of the destination server. In response to the determined processing capacity of the destination mail server, and the time in which the emails must be sent by, the emails are either sent, or a negotiation is performed with each of the destination servers, to determine an available time. Therefore, each destination server can control the time in which it receives and processes the emails. Therefore, avoiding large amounts of emails 'hitting' the destination servers, at a time when the destination servers are already very busy and available processing capacity is of a premium.
