Winwebmail building a simple webmail system

This is a piece of web mail model code, the function is not very strong, but the structure is relatively complete, the main functions such as viewing folders, view letters, replies, letters are. However, the program does not consider the attachment interpretation and transmission problems. (the original is here). Only recommended for those who want to understand the webmail programming users to do a reference. More Perfect Webmail Please come here to find.
Note: The HTTP authentication feature is used in the program, which needs to be used with the Apache server.

Save the following code as INDEX.PHP3, IMAPFUNCS.PHL
Configure $m_host = "localhost" in the IMAPFUNCS.PHL file; $M _mailserver = "transit.fast.no";
Then browse index.php3.
