This is a Demo code of Web Mail. It is not very functional, but has a complete structure. Its main functions include viewing folders, viewing letters, replying to letters, and writing letters. However, the program does not consider the issue of attachment interpretation and sending. (The original article is here ). It is only recommended to users who want to know Webmail programming for reference. For more comprehensive Webmail, please visit here.
Note: http authentication is used in the program. This function must be used with the apache server.
