| 2 | .SH NAME |
| 3 | qmail-send \- deliver mail messages from the queue |
| 4 | .SH SYNOPSIS |
| 5 | .B qmail-send |
| 6 | .SH DESCRIPTION |
| 7 | .B qmail-send |
| 8 | handles messages placed into the outgoing queue by |
| 9 | .BR qmail-queue . |
| 10 | It uses |
| 11 | .B qmail-lspawn |
| 12 | to deliver messages to local recipients and |
| 13 | .B qmail-rspawn |
| 14 | to deliver messages to remote recipients. |
| 15 | If a message is temporarily undeliverable to one or more addresses, |
| 16 | .B qmail-send |
| 17 | leaves it in the queue and tries the addresses again later. |
| 18 | |
| 19 | .B qmail-send |
| 20 | prints a readable record of its activities to descriptor 0. |
| 21 | It writes commands to |
| 22 | .BR qmail-lspawn , |
| 23 | .BR qmail-rspawn , |
| 24 | and |
| 25 | .B qmail-clean |
| 26 | on descriptors 1, 3, and 5, |
| 27 | and reads responses from descriptors 2, 4, and 6. |
| 28 | .B qmail-send |
| 29 | is responsible for avoiding deadlock. |
| 30 | |
| 31 | If |
| 32 | .B qmail-send |
| 33 | receives a TERM signal, |
| 34 | it will exit cleanly, after waiting |
| 35 | (possibly more than a minute) |
| 36 | for current delivery attempts to finish. |
| 37 | |
| 38 | If |
| 39 | .B qmail-send |
| 40 | receives an ALRM signal, |
| 41 | it will reschedule every message in the queue for immediate delivery. |
| 42 | .SH "CONTROL FILES" |
| 43 | .B WARNING: |
| 44 | .B qmail-send |
| 45 | reads its control files only when it starts. |
| 46 | If you change the control files, |
| 47 | you must stop and restart |
| 48 | .BR qmail-send . |
| 49 | Exception: |
| 50 | If |
| 51 | .B qmail-send |
| 52 | receives a HUP signal, |
| 53 | it will reread |
| 54 | .I locals |
| 55 | and |
| 56 | .IR virtualdomains . |
| 57 | .TP 5 |
| 58 | .I bouncefrom |
| 59 | Bounce username. |
| 60 | Default: |
| 61 | .BR MAILER-DAEMON . |
| 62 | .TP 5 |
| 63 | .I bouncehost |
| 64 | Bounce host. |
| 65 | Default: |
| 66 | .IR me , |
| 67 | if that is supplied; |
| 68 | otherwise the literal name |
| 69 | .BR bouncehost , |
| 70 | which is probably not what you want. |
| 71 | If a message is permanently undeliverable, |
| 72 | .B qmail-send |
| 73 | sends a |
| 74 | .B single-bounce |
| 75 | notice back to the message's envelope sender. |
| 76 | The notice is |
| 77 | .B From: \fIbouncefrom\fB@\fIbouncehost\fR, |
| 78 | although its envelope sender is empty. |
| 79 | .TP 5 |
| 80 | .I concurrencylocal |
| 81 | Maximum number of simultaneous local delivery attempts. |
| 82 | Default: 10. |
| 83 | If 0, local deliveries will be put on hold. |
| 84 | .I concurrencylocal |
| 85 | is limited at compile time to |
| 86 | SPAWN. |
| 87 | .TP 5 |
| 88 | .I concurrencyremote |
| 89 | Maximum number of simultaneous remote delivery attempts. |
| 90 | Default: 20. |
| 91 | If 0, remote deliveries will be put on hold. |
| 92 | .I concurrencyremote |
| 93 | is limited at compile time to |
| 94 | SPAWN. |
| 95 | .TP 5 |
| 96 | .I doublebouncehost |
| 97 | Double-bounce host. |
| 98 | Default: |
| 99 | .IR me , |
| 100 | if that is supplied; |
| 101 | otherwise the literal name |
| 102 | .BR doublebouncehost , |
| 103 | which is probably not what you want. |
| 104 | .TP 5 |
| 105 | .I doublebounceto |
| 106 | User to receive double-bounces. |
| 107 | Default: |
| 108 | .BR postmaster . |
| 109 | If a single-bounce notice is permanently undeliverable, |
| 110 | .B qmail-send |
| 111 | sends a |
| 112 | .B double-bounce |
| 113 | notice to |
| 114 | .IR doublebounceto\fB@\fIdoublebouncehost . |
| 115 | (If that bounces, |
| 116 | .B qmail-send |
| 117 | gives up.) |
| 118 | .TP 5 |
| 119 | .I envnoathost |
| 120 | Presumed domain name for addresses without @ signs. |
| 121 | Default: |
| 122 | .IR me , |
| 123 | if that is supplied; |
| 124 | otherwise the literal name |
| 125 | .BR envnoathost , |
| 126 | which is probably not what you want. |
| 127 | If |
| 128 | .B qmail-send |
| 129 | sees an envelope recipient address without an @ sign, |
| 130 | it appends |
| 131 | .B @\fIenvnoathost\fR. |
| 132 | .TP 5 |
| 133 | .I locals |
| 134 | List of domain names that the current host |
| 135 | receives mail for, |
| 136 | one per line. |
| 137 | Default: |
| 138 | .IR me , |
| 139 | if that is supplied; |
| 140 | otherwise |
| 141 | .B qmail-send |
| 142 | refuses to run. |
| 143 | An address |
| 144 | .I user@domain |
| 145 | is considered local if |
| 146 | .I domain |
| 147 | is listed in |
| 148 | .IR locals . |
| 149 | .TP 5 |
| 150 | .I percenthack |
| 151 | List of domain names where the percent hack is applied. |
| 152 | If |
| 153 | .I domain |
| 154 | is listed in |
| 155 | .IR percenthack , |
| 156 | any address of the form |
| 157 | .I user%fqdn@domain |
| 158 | is rewritten as |
| 159 | .IR user@fqdn . |
| 160 | .I user |
| 161 | may contain %, |
| 162 | so the percent hack may be applied repeatedly. |
| 163 | .B qmail-send |
| 164 | handles |
| 165 | .I percenthack |
| 166 | before |
| 167 | .IR locals . |
| 168 | .TP 5 |
| 169 | .I queuelifetime |
| 170 | Number of seconds |
| 171 | a message can stay in the queue. |
| 172 | Default: 604800 (one week). |
| 173 | After this time expires, |
| 174 | .B qmail-send |
| 175 | will try the message once more, |
| 176 | but it will treat any temporary delivery failures as |
| 177 | permanent failures. |
| 178 | .TP 5 |
| 179 | .I virtualdomains |
| 180 | List of virtual users or domains, one per line. |
| 181 | A virtual user has the form |
| 182 | .IR user\fB@\fIdomain\fB:\fIprepend , |
| 183 | without any extra spaces. |
| 184 | When |
| 185 | .B qmail-send |
| 186 | sees the recipient address |
| 187 | .IR user\fB@\fIdomain , |
| 188 | it converts it to |
| 189 | .I prepend\fB-\fIuser\fB@\fIdomain |
| 190 | and treats it as local. |
| 191 | |
| 192 | A virtual domain has the form |
| 193 | .IR domain\fB:\fIprepend . |
| 194 | It applies to any recipient address at |
| 195 | .IR domain . |
| 196 | For example, if |
| 197 | |
| 198 | .EX |
| 199 | nowhere.mil:joeBREAKfoo |
| 200 | .EE |
| 201 | |
| 202 | is in |
| 203 | .IR virtualdomains , |
| 204 | and a message arrives for |
| 205 | .BR info@nowhere.mil , |
| 206 | .B qmail-send |
| 207 | will rewrite the recipient address as |
| 208 | .B joeBREAKfoo-info@nowhere.mil |
| 209 | and deliver the message locally. |
| 210 | |
| 211 | .I virtualdomains |
| 212 | may contain wildcards: |
| 213 | |
| 214 | .EX |
| 215 | .fax:uucpBREAKfax |
| 216 | :aliasBREAKcatchall |
| 217 | .nowhere.mil:joeBREAKfoo-host |
| 218 | .EE |
| 219 | |
| 220 | .I virtualdomains |
| 221 | may also contain exceptions: |
| 222 | an empty |
| 223 | .I prepend |
| 224 | means that |
| 225 | .I domain |
| 226 | is not a virtual domain. |
| 227 | |
| 228 | .B qmail-send |
| 229 | handles |
| 230 | .I virtualdomains |
| 231 | after |
| 232 | .IR locals : |
| 233 | if a domain is listed in |
| 234 | .IR locals , |
| 235 | .I virtualdomains |
| 236 | does not apply. |
