Description:
------------
When mailbox or subfolder larger than 4G, the imap_mailboxmsginfo() will return wrong size. It is because the msize for accumulate the RFC822.SIZE overflow beyond 4G due to 32bit integer. By changing the unsigned int to unsigned long, the msize will be calculated correctly.
