Abstract: The present invention involves a method of managing an update of an old e-mail address to a new e-mail address of a first party via a first system, wherein the update is managed by a second system for a second party. The invention includes providing inputted information of the update in the first system and sending the inputted information to the second system. The inputted information represents the update and is recognizable by the second system. The method further includes configuring the information of the update into the second system to monitor outgoing email addresses of subsequent email messages and sensing an outgoing email address of a subsequent email message sent from the second system. The method further includes redirecting the subsequent email message to the new email address of the first client, if the outgoing email address is determined to be the old email address of the first client.
