# qmail-lspawn(8)

schedule local deliveries

## NAME

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.
