NAME
qmail-send - deliver mail messages from the queue
SYNOPSISqmail-sendDESCRIPTIONqmail-send handles messages placed into the outgoing queue
by qmail-queue. It uses qmail-lspawn to deliver messages to
local recipients and qmail-rspawn to deliver messages to
remote recipients. If a message is temporarily undeliver-
able to one or more addresses, qmail-send leaves it in the
queue and tries the addresses again later.
qmail-send prints a readable record of its activities to
descriptor 0. It writes commands to qmail-lspawn, qmail-rspawn, and qmail-clean on descriptors 1, 3, and 5, and
reads responses from descriptors 2, 4, and 6. qmail-send is
responsible for avoiding deadlock.
If qmail-send receives a TERM signal, it will exit cleanly,
after waiting (possibly more than a minute) for current
delivery attempts to finish.
If qmail-send receives an ALRM signal, it will reschedule
every message in the queue for immediate delivery.
CONTROLFILESWARNING:qmail-send reads its control files only when it
starts. If you change the control files, you must stop and
restart qmail-send. Exception: If qmail-send receives a
HUP signal, it will reread locals and virtualdomains.
bouncefrom
Bounce username. Default: MAILER-DAEMON.
bouncehost
Bounce host. Default: me, if that is supplied; other-
wise the literal name bouncehost, which is probably not
what you want. If a message is permanently undeliver-
able, qmail-send sends a single-bounce notice back to
the message's envelope sender. The notice is From:bouncefrom@bouncehost, although its envelope sender is
empty.
concurrencylocal
Maximum number of simultaneous local delivery attempts.
Default: 10. If 0, local deliveries will be put on
hold. concurrencylocal is limited at compile time to
120.
concurrencyremote

Maximum number of simultaneous remote delivery
attempts. Default: 20. If 0, remote deliveries will
be put on hold. concurrencyremote is limited at com-
pile time to 120.
doublebouncehost
Double-bounce host. Default: me, if that is supplied;
otherwise the literal name doublebouncehost, which is
probably not what you want.
doublebounceto
User to receive double-bounces. Default: postmaster.
If a single-bounce notice is permanently undeliverable,
qmail-send sends a double-bounce notice to
doublebounceto@doublebouncehost. (If that bounces,
qmail-send gives up.)
envnoathost
Presumed domain name for addresses without @ signs.
Default: me, if that is supplied; otherwise the
literal name envnoathost, which is probably not what
you want. If qmail-send sees an envelope recipient
address without an @ sign, it appends @envnoathost.
locals
List of domain names that the current host receives
mail for, one per line. Default: me, if that is sup-
plied; otherwise qmail-send refuses to run. An address
user@domain is considered local if domain is listed in
locals.
percenthack
List of domain names where the percent hack is applied.
If domain is listed in percenthack, any address of the
form user%fqdn@domain is rewritten as user@fqdn. user
may contain %, so the percent hack may be applied
repeatedly. qmail-send handles percenthack before
recipientmap.
queuelifetime
Number of seconds a message can stay in the queue.
Default: 604800 (one week). After this time expires,
qmail-send will try the message once more, but it will
treat any temporary delivery failures as permanent
failures.
recipientmap
List of redirections, one per line. Each redirection
has the form recipient:rewritten, without any extra
spaces. When qmail-send sees the address recipient, it
replaces it with rewritten. Both recipient and rewrit-ten must include domain names. qmail-send handles

recipientmap before locals.
virtualdomains
List of virtual domains, one per line. Each virtual
domain has the form domain:prepend, without any extra
spaces. When qmail-send sees a recipient address at
domain, say user@domain, it converts it to prepend-user@domain and treats it as local. For example, if
nowhere.mil:joe-foo
is in virtualdomains, and a message arrives for
info@nowhere.mil, qmail-send will rewrite the recipient
address as joe-foo-info@nowhere.mil and deliver the
message locally. virtualdomains may contain wildcards:
.fax:uucp-fax
:alias-catchall
.nowhere.mil:joe-foo-host
virtualdomains may also contain exceptions: an empty
prepend means that domain is not a virtual domain.
qmail-send handles virtualdomains after locals: if a
domain is listed in locals, virtualdomains does not
apply.
