qmail-lspawn - schedule local deliveries SYNOPSIS
qmail-lspawn defaultdelivery DESCRIPTION
qmail-lspawn reads a series of local delivery commands from descriptor 0, invokes qmail-local to perform the deliveries, and prints the results to descriptor 1. It passes defaultdelivery to qmail-local as the default delivery instruction. qmail-lspawn invokes qmail-local asynchronously, so the results may not be in the same order as the commands. For each recipient address, qmail-lspawn finds out which local user controls that address. It first checks the qmail-users mechanism; if the address is not listed there, it invokes qmail-getpw. qmail-lspawn then runs qmail-local under the user's uid and gid. It does not set up any supplementary groups. qmail-lspawn treats an empty mailbox name as a trash address. SEE ALSO

qmail-start - turn on mail delivery SYNOPSIS
qmail-start [ defaultdelivery [ logger arg ... ] ] DESCRIPTION
qmail-start invokes qmail-send, qmail-lspawn, qmail-rspawn, and qmail-clean, under the proper uids and gids. These four daemons cooperate to deliver messages from the queue. qmail-start arranges for qmail-send's activity record to be sent to qmail-start's output. See qmail-log(5) for the format of the activity record. Other than this, qmail-start does not print anything, even on failure. If defaultdelivery is supplied, qmail-start passes it to qmail-lspawn. If logger is supplied, qmail-start invokes logger with the given arguments, and feeds qmail-send's activity record through logger. Environment variables given to qmail-start will eventually be passed on to qmail-local, so make sure to clean up the environment if you run qmail-start manually: # env - PATH="/var/lib/qmail/bin:$PATH" qmail-start ./Mailbox splogger qmail & (all on one line) Resource limits, controlling ttys, et al. are also passed from qmail-start to qmail-local. Note that qmail-send normally juggles several simultaneous deliveries. To reduce qmail-send's impact on other programs, you can run qmail- start with a low priority. SEE ALSO
