3 qmail-send \- deliver mail messages from the queue
8 handles messages placed into the outgoing queue by
12 to deliver messages to local recipients and
14 to deliver messages to remote recipients.
15 If a message is temporarily undeliverable to one or more addresses,
17 leaves it in the queue and tries the addresses again later.
20 prints a readable record of its activities to descriptor 0.
26 on descriptors 1, 3, and 5,
27 and reads responses from descriptors 2, 4, and 6.
29 is responsible for avoiding deadlock.
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.
40 receives an ALRM signal,
41 it will reschedule every message in the queue for immediate delivery.
45 reads its control files only when it starts.
46 If you change the control files,
47 you must stop and restart

89 Maximum number of simultaneous remote delivery attempts.
91 If 0, remote deliveries will be put on hold.
93 is limited at compile time to
101 otherwise the literal name
102 .BR doublebouncehost ,
103 which is probably not what you want.
106 User to receive double-bounces.
109 If a single-bounce notice is permanently undeliverable,
114 .IR doublebounceto\fB@\fIdoublebouncehost .
120 Presumed domain name for addresses without @ signs.
124 otherwise the literal name

171 a message can stay in the queue.
172 Default: 604800 (one week).
173 After this time expires,
175 will try the message once more,
176 but it will treat any temporary delivery failures as
180 List of redirections, one per line.
181 Each redirection has the form
182 .IR recipient\fB:\fIrewritten ,
183 without any extra spaces.
194 must include domain names.
202 List of virtual domains, one per line.
203 Each virtual domain has the form

205 without any extra spaces.
208 sees a recipient address at
211 .IR user\fB@\fIdomain ,
213 .I prepend\fB-\fIuser\fB@\fIdomain
214 and treats it as local.
218 nowhere.mil:joeBREAKfoo
223 and a message arrives for
224 .BR info@nowhere.mil ,
226 will rewrite the recipient address as
227 .B joeBREAKfoo-info@nowhere.mil
228 and deliver the message locally.
230 may contain wildcards:
235 .nowhere.mil:joeBREAKfoo-host
239 may also contain exceptions:
