9 Postfix local mail pickup
13 \fBpickup\fR [generic Postfix daemon options]
17 The \fBpickup\fR(8) daemon waits for hints that new mail has been
18 dropped into the \fBmaildrop\fR directory, and feeds it into the
19 \fBcleanup\fR(8) daemon.
20 Ill-formatted files are deleted without notifying the originator.
21 This program expects to be run from the \fBmaster\fR(8) process
28 None. The \fBpickup\fR(8) daemon does not interact with
35 The \fBpickup\fR(8) daemon is moderately security sensitive. It runs
36 with fixed low privilege and can run in a chrooted environment.
37 However, the program reads files from potentially hostile users.
38 The \fBpickup\fR(8) daemon opens no files for writing, is careful about
39 what files it opens for reading, and does not actually touch any data
40 that is sent to its public service endpoint.
44 Problems and transactions are logged to \fBsyslogd\fR(8).
48 The \fBpickup\fR(8) daemon copies mail from file to the \fBcleanup\fR(8)
49 daemon. It could avoid message copying overhead by sending a file
50 descriptor instead of file data, but then the already complex
51 \fBcleanup\fR(8) daemon would have to deal with unfiltered user data.
52 .SH "CONFIGURATION PARAMETERS"
57 As the \fBpickup\fR(8) daemon is a relatively long-running process, up
58 to an hour may pass before a \fBmain.cf\fR change takes effect.
59 Use the command "\fBpostfix reload\fR" command to speed up a change.
61 The text below provides only a parameter summary. See
62 \fBpostconf\fR(5) for more details including examples.
63 .SH "CONTENT INSPECTION CONTROLS"
68 .IP "\fBcontent_filter (empty)\fR"
69 The name of a mail delivery transport that filters mail after
71 .IP "\fBreceive_override_options (empty)\fR"

84 communication channel.
85 .IP "\fBline_length_limit (2048)\fR"

87 this length; upon delivery, long lines are reconstructed.
88 .IP "\fBmax_idle (100s)\fR"

90 for an incoming connection before terminating voluntarily.
91 .IP "\fBmax_use (100)\fR"

102 .IP "\fBsyslog_name (see 'postconf -d' output)\fR"
103 The mail system name that is prepended to the process name in syslog
