Append a string message to a specified mailbox (PHP 3, PHP 4, PHP 5)
bool imap_append ( resource imap_stream, string mbox, string message [, string options] )

imap_append() appends a string message to the specified mailbox mbox. If the optional options is specified, writes the options to that mailbox also.

如果成功则返回 TRUE,失败则返回 FALSE

When talking to the Cyrus IMAP server, you must use "\r\n" as your end-of-line terminator instead of "\n" or the operation will fail.
