The \fBpickup\fR(8) daemon does not interact with +the outside world. +.SH "SECURITY" +.na +.nf +.ad +.fi +The \fBpickup\fR(8) daemon is moderately security sensitive. It runs +with fixed low privilege and can run in a chrooted environment. +However, the program reads files from potentially hostile users. +The \fBpickup\fR(8) daemon opens no files for writing, is careful about +what files it opens for reading, and does not actually touch any data +that is sent to its public service endpoint. +.SH DIAGNOSTICS +.ad +.fi +Problems and transactions are logged to \fBsyslogd\fR(8) +or \fBpostlogd\fR(8). +.SH BUGS +.ad +.fi +The \fBpickup\fR(8) daemon copies mail from file to the \fBcleanup\fR(8) +daemon. It could avoid message copying overhead by sending a file +descriptor instead of file data, but then the already complex +\fBcleanup\fR(8) daemon would have to deal with unfiltered user data. +.SH "CONFIGURATION PARAMETERS" +.na +.nf +.ad +.fi +As the \fBpickup\fR(8) daemon is a relatively long\-running process, up +to an hour may pass before a \fBmain.cf\fR change takes effect. +Use the command "\fBpostfix reload\fR" command to speed up a change. + +The text below provides only a parameter summary. See +\fBpostconf\fR(5) for more details including examples. +.SH "CONTENT INSPECTION CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBcontent_filter (empty)\fR" +After the message is queued, send the entire message to the +specified \fItransport:destination\fR. +.IP "\fBreceive_override_options (empty)\fR" +Enable or disable recipient validation, built\-in content +filtering, or address mapping. +.SH "MISCELLANEOUS CONTROLS" +.na +.nf +.ad +.fi +.IP "\fBconfig_directory (see 'postconf -d' output)\fR" +The default location of the Postfix main.cf and master.cf +configuration files. +.IP "\fBipc_timeout (3600s)\fR" +The time limit for sending or receiving information over an internal +communication channel. +.IP "\fBline_length_limit (2048)\fR" +Upon input, long lines are chopped up into pieces of at most +this length; upon delivery, long lines are reconstructed. +.IP "\fBmax_idle (100s)\fR" +The maximum amount of time that an idle Postfix daemon process waits +for an incoming connection before terminating voluntarily. +.IP "\fBmax_use (100)\fR" +The maximal number of incoming connections that a Postfix daemon +process will service before terminating voluntarily. +.IP "\fBprocess_id (read\-only)\fR" +The process ID of a Postfix command or daemon process. +.IP "\fBprocess_name (read\-only)\fR" +The process name of a Postfix command or daemon process. +.IP "\fBqueue_directory (see 'postconf -d' output)\fR" +The location of the Postfix top\-level queue directory. +.IP "\fBsyslog_facility (mail)\fR" +The syslog facility of Postfix logging. +.IP "\fBsyslog_name (see 'postconf -d' output)\fR" +A prefix that is prepended to the process name in syslog +records, so that, for example, "smtpd" becomes "prefix/smtpd". +.PP +Available in Postfix 3.3 and later: +.IP "\fBservice_name (read\-only)\fR" +The master.cf service name of a Postfix daemon process. +.PP +Available in Postfix 3.5 and later: +.IP "\fBinfo_log_address_format (external)\fR" +The email address form that will be used in non\-debug logging +(info, warning, etc.). +.SH "SEE ALSO" +.na +.nf +cleanup(8), message canonicalization +sendmail(1), Sendmail\-compatible interface +postdrop(1), mail posting agent +postconf(5), configuration parameters +master(5), generic daemon options +master(8), process manager +postlogd(8), Postfix logging +syslogd(8), system logging +.SH "LICENSE" +.na +.nf +.ad +.fi +The Secure Mailer license must be distributed with this software. +.SH "AUTHOR(S)" +.na +.nf +Wietse Venema +IBM T.J.
