Page 2 of 3 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). BUGS ENVIRONMENT MAIL_DEBUG After initialization, start a debugger as specified with the debugger_command configuration parameter in the main.cf configuration file. MAIL_CONFIG Directory with Postfix configuration files. CONFIGURATION PARAMETERS The following main.cf parameters are especially relevant to this program. See the Postfix main.cf file for syntax details and for default values. Use the postfix reload command after a configuration change. Miscellaneous import_environment export_environment Lists of names of environment parameters that can be imported from (exported to) non-Postfix processes. mail_owner The owner of the mail queue and of most Postfix processes. command_directory Directory with Postfix support programs. daemon_directory Directory with Postfix daemon programs. queue_directory Top-level directory of the Postfix queue. This is also the root directory of Postfix daemons that run chrooted. Resource controls default_process_limit Default limit for the number of simultaneous child processes that provide a given service. max_idle Limit the time in seconds that a child process waits between service requests. max_use Limit the number of service requests handled by a child process. http://www.porcupine.org/postfix-mirror/master.8.html 6/26/01
