| 10 | This file contains a template local_scan() function that just returns ACCEPT. | |
| 11 | If you want to implement your own version, you should copy this file to, say | |
| 12 | Local/local_scan.c, and edit the copy. To use your version instead of the | |
| 13 | default, you must set | |
| 14 | ||
| 15 | LOCAL_SCAN_SOURCE=Local/local_scan.c | |
| 16 | ||
| 17 | in your Local/Makefile. This makes it easy to copy your version for use with | |
| 18 | subsequent Exim releases. | |
| 19 | ||
| 20 | For a full description of the API to this function, see the Exim specification. | |

| 34 | fd The file descriptor of the open -D file, which contains the | |
| 35 | body of the message. The file is open for reading and | |
| 36 | writing, but modifying it is dangerous and not recommended. | |

| 39 | order to return a text string. It is initialized to NULL. | |

| 45 | saved in $local_scan_data. | |
| 46 | ||
| 47 | LOCAL_SCAN_REJECT | |
| 48 | The message is to be rejected. The returned text is used | |
| 49 | in the rejection message. | |
| 50 | ||
| 51 | LOCAL_SCAN_TEMPREJECT | |
| 52 | This specifies a temporary rejection. The returned text | |
| 53 | is used in the rejection message. | |
