SIGTERM
Upon receipt of a TERM signal (e.g., after postfix
abort), the master process passes the signal on to
its child processes and terminates. This is useful
for an emergency shutdown. Normally one would terminate
only the master (postfix stop) and allow
running processes to finish what they are doing.
DIAGNOSTICS
Problems are reported to syslogd(8).
