II,ProgramDesign Analysis:

1. Multiple users are supported. You need to design logon pages and administrator management pages (or how to manage users ?) User information page.
2. Multiple folders are supported, and a folder tree is required. For example, a folder tree is displayed on the left of emails such as 163.
3. Multiple mailbox settings are supported, so you must set the mailbox page and add the mailbox settings list page.
4. Of course, the mail management page is still inseparable.
5. Since multi-thread sending and receiving is supported, we need to set a mail sending and receiving Thread class, which we can call through WebService.
6. In the end, the entire T-frame will not be used as an alternative.

Well, this graph is free of charge. If you need other functions, add them.
