这是一段Web Mail的示范代码，功能不是很强，但是结构还比较完整，主要的功能如查看文件夹，查看信件，回复，写信都有。但是程序中没有考虑附件解读和发送的问题。 (原文在 这里)。仅推荐给希望了解Webmail编程的网友做个参考。更加完善的Webmail请大家到 这里查找。
请注意：程序中使用了http认证功能，此功能需配合apache服务器使用。

将以下代码分别存为 index.php3, imapfuncs.phl
配置imapfuncs.phl文件中的$M_HOST = "localhost"; $M_MAILSERVER = "transit.fast.no";
然后浏览 index.php3 即可.
--------------------------------------------------------------------------------
index.php3
/* $Id: index.php3,v 1.3 1999/04/14 12:12:32 borud Exp $ */
/* load the IMAP library functions we\'ve written */
include("imapfuncs.phl");
m_login($m);
?>
<?PHP echo "$M_SYSNAME"; ?>
if ($cmd == "delete") {
m_delete($marked, $m);
m_list($m);
}
elseif ($cmd == "display") {
m_display($n, $m);
}
elseif ($cmd == "compose" || $cmd == "reply") {
m_compose($n, $m);
}
elseif ($cmd == "send") {
m_send($to, $subject, $body);
m_list($m);
}
else {
m_list($m);
}
