Abstract

Disclosed is a system for accessing a folder of messages in a mail server, such as an inbox folder, outbox folder, draft message folder, etc. This disclosed system is especially suited for "offline" type protocols, such as POP3. A client computer establishes a first connection with a mail server including the folder of messages over a network. The client computer communicates a command to the mail server to parse messages in the folder to obtain message headers. The message headers are then downloaded to the client computer. After downloading the message headers, the first connection between the client computer and the mail server is terminated. The client computer may then be used to select at least one displayed header. After message headers are selected, a second connection is established between the client computer and the mail server. The client computer communicates a command to the mail server to retrieve a body for each message whose header was selected. The selected message bodies are then downloaded to the client computer. After downloading message bodies, the client computer communicates a command to the mail server to delete the selected messages from the folder in the mail server. The client computer then communicates a command to the mail server to terminate the second connection between the client computer and the mail server.
