qmail-limits - artificial limits in the qmail system
The qmail system is able to handle messages of any size,
addresses of any size, mailing lists of any size, and so on,
except as limited by the available memory and disk space.
However, it imposes certain artificial limits:
1. qmail-lspawn silently limits the number of simultaneous
local deliveries to SPAWN. qmail-rspawn silently
limits the number of simultaneous remote deliveries to
2. qmail-queue rejects any message with an envelope
address longer than 1000 characters.
3. qmail-lspawn truncates any overly long error report
from a delivery program. It appends a note saying that
it did so.
