| 7 | .SH DESCRIPTION |
| 8 | The |
| 9 | .B qmail-checkspam |
| 10 | program provides the same interface as |
| 11 | .BR qmail-queue (8). |
| 12 | It reads a message on file descriptor 0, and passes it to |
| 13 | .BR spamd (8). |
| 14 | If |
| 15 | .B spamd |
| 16 | thinks the message is spam, then |
| 17 | .B qmail-checkspam |
| 18 | exits 31, indicating a permanent refusal. |
| 19 | Otherwise, |
| 20 | .B qmail-checkspam |
| 21 | feeds the message, augmented by SpamAssassin's |
| 22 | .B X-Spam-Status |
| 23 | header, to |
| 24 | .BR qmail-queue (8). |
