| | | * The Mail_mimeDecode class is used to decode mail/mime messages |
| | | * |
| | | * This class will parse a raw mime email and return |
| | | * the structure. Returned structure is similar to |
| | | * that returned by imap_fetchstructure(). |
| | | * |
| | | * +----------------------------- IMPORTANT ------------------------------+ |
| | | * | Usage of this class compared to native php extensions such as | |
| | | * | mailparse or imap, is slow and may be feature deficient. If available| |
| | | * | you are STRONGLY recommended to use the php extensions. | |
