| 2 | .SH NAME |
| 3 | qmail-queue \- queue a mail message for delivery |
| 4 | .SH SYNOPSIS |
| 5 | .B qmail-queue |
| 6 | .SH DESCRIPTION |
| 7 | .B qmail-queue |
| 8 | reads a mail message from descriptor 0. |
| 9 | It then reads envelope information from descriptor 1. |
| 10 | It places the message into the outgoing queue |
| 11 | for future delivery by |
| 12 | .BR qmail-send . |
| 13 | |
| 14 | The envelope information is |
| 15 | an envelope sender address |
| 16 | followed by a list of envelope recipient addresses. |
| 17 | The sender address is preceded by the letter F |
| 18 | and terminated by a 0 byte. |
| 19 | Each recipient address is preceded by the letter T |
| 20 | and terminated by a 0 byte. |
| 21 | The list of recipient addresses is terminated by an extra 0 byte. |
| 22 | If |
| 23 | .B qmail-queue |
| 24 | sees end-of-file before the extra 0 byte, |
| 25 | it aborts without placing the message into the queue. |
| 26 | |
| 27 | Every envelope recipient address |
| 28 | should contain a username, |
| 29 | an @ sign, |
| 30 | and a fully qualified domain name. |
| 31 | |
| 32 | .B qmail-queue |
| 33 | always adds a |
| 34 | .B Received |
| 35 | line to the top of the message. |
| 36 | Other than this, |
| 37 | .B qmail-queue |
| 38 | does not inspect the message |
| 39 | and does not enforce any restrictions on its contents. |
| 40 | However, the recipients probably expect to see a proper header, |
| 41 | as described in |
| 42 | .BR qmail-header(5) . |
| 43 | .SH "FILESYSTEM RESTRICTIONS" |
| 44 | .B qmail-queue |
| 45 | imposes two constraints on the queue structure: |
| 46 | each |
| 47 | .B mess |
| 48 | subdirectory must be in the same filesystem as the |
| 49 | .B pid |
| 50 | directory; and each |
| 51 | .B todo |
| 52 | subdirectory must be in the same filesystem as the |
| 53 | .B intd |
| 54 | directory. |
| 55 | .SH "EXIT CODES" |
| 56 | .B qmail-queue |
| 57 | does not print diagnostics. |
| 58 | It exits |
| 59 | 0 if |
| 60 | it has successfully queued the message. |
| 61 | It exits between 1 and 99 if |
| 62 | it has failed to queue the message. |
| 63 | |
