US Patent 7979500 Email composition and processing

A computer implemented user interface allows composition of an electronic mail message. A user selects at least one pre-existing email from an email inbox. An envelope is then created by parsing each of the selected pre-existing emails. The pre-existing email is displayed as a tree structure comprising an envelope with at least a label sub-node in a new email view. A new email is composed by selecting parts from the tree structure. The sub-nodes may further comprise a content sub-node. The content sub-node further comprises multi-media parts, and the new email body is composed by selecting parts from the content sub-node.
