See also the MAILCONFIG environment setting below.\n\n#### -r\n\nreporting status information on standard output. This is currently the only supported\nmethod.\n\n#### -v -v\n\nincreasingly verbose. As of Postfix 2.3, this option is available for the super-user\nonly.\n\n### SECURITY\n\nThe command is designed to run with set-group ID privileges, so that it can write to the\nmaildrop queue directory and so that it can connect to Postfix daemon processes.\n\n### DIAGNOSTICS\n\nFatal errors: malformed input, I/O error, out of memory. Problems are logged to syslogd(8) or\npostlogd(8) and to the standard error stream. When the input is incomplete, or when the\nprocess receives a HUP, INT, QUIT or TERM signal, the queue file is deleted.\n\n### ENVIRONMENT\n\nMAILCONFIG\nDirectory with the main.cf file. In order to avoid exploitation of set-group ID privi‐\nleges, a non-standard directory is allowed only if:\n\n• The name is listed in the standard main.cf file with the alternateconfigdi‐‐\nrectories configuration parameter.\n\n• The command is invoked by the super-user.\n\n### CONFIGURATION PARAMETERS\n\nThe following main.cf parameters are especially relevant to this program. The text below\nprovides only a parameter summary. See postconf(5) for more details including examples.\n\nalternateconfigdirectories (empty)\nA list of non-default Postfix configuration directories that may be specified with \"-c\nconfigdirectory\" on the command line (in the case of sendmail(1), with the \"-C\" op‐\ntion), or via the MAILCONFIG environment parameter.\n\nconfigdirectory (see 'postconf -d' output)\nThe default location of the Postfix main.cf and master.cf configuration files.\n\nimportenvironment (see 'postconf -d' output)\nThe list of environment parameters that a privileged Postfix process will import from\na non-Postfix parent process, or name=value environment overrides.\n\nqueuedirectory (see 'postconf -d' output)\nThe location of the Postfix top-level queue directory.\n\nsyslogfacility (mail)\nThe syslog facility of Postfix logging.\n\nsyslogname (see 'postconf -d' output)\nA prefix that is prepended to the process name in syslog records, so that, for exam‐\nple, \"smtpd\" becomes \"prefix/smtpd\".\n\ntriggertimeout (10s)\nThe time limit for sending a trigger to a Postfix daemon (for example, the pickup(8)\nor qmgr(8) daemon).\n\nAvailable in Postfix version 2.2 and later:\n\nauthorizedsubmitusers (static:anyone)\nList of users who are authorized to submit mail with the sendmail(1) command (and with\nthe privileged postdrop(1) helper command).\n\nAvailable in Postfix version 3.6 and later:\n\nlocalloginsendermaps (static:*)\nA list of lookup tables that are searched by the UNIX login name, and that return a\nlist of allowed envelope sender patterns separated by space or comma.\n\nemptyaddresslocalloginsendermapslookupkey (<>)\nThe lookup key to be used in localloginsendermaps tables, instead of the null\nsender address.\n\nrecipientdelimiter (empty)\nThe set of characters that can separate an email address localpart, user name, or a\n.forward file name from its extension.\n\n### FILES\n\n/var/spool/postfix/maildrop, maildrop queue\n\n### SEE ALSO\n\nsendmail(1), compatibility interface\npostconf(5), configuration parameters\npostlogd(8), Postfix logging\nsyslogd(8), system logging\n\n### LICENSE\n\nThe Secure Mailer license must be distributed with this software.\n\nAUTHOR(S)\nWietse Venema\nIBM T.J.
