<b>SYSTEM-WIDE AND USER-LEVEL ALIASING</b>

The system administrator can set up one or more system-

<b><a href="postconf.5.html#forward_path">ward_path</a></b> configuration parameter. Upon delivery, the
46
local delivery agent tries each pathname in the list until

Delivery via ~/.<b>forward</b> files is done with the privileges

<b>MAILBOX DELIVERY</b>
101
The default per-user mailbox is a file in the UNIX mail
102
spool directory (<b>/var/mail/</b><i>user</i> or <b>/var/spool/mail/</b><i>user</i>);
103
the location can be specified with the <b><a href="postconf.5.html#mail_spool_directory">mail_spool_direc</a>-</b>
104
<b><a href="postconf.5.html#mail_spool_directory">tory</a></b> configuration parameter. Specify a name ending in <b>/</b>
105
for <b>qmail</b>-compatible <b>maildir</b> delivery.
107
Alternatively, the per-user mailbox can be a file in the
108
user's home directory with a name specified via the
109
<b><a href="postconf.5.html#home_mailbox">home_mailbox</a></b> configuration parameter. Specify a relative
110
path name. Specify a name ending in <b>/</b> for <b>qmail</b>-compatible
111
<b>maildir</b> delivery.

Mailbox delivery can be delegated to an external command
114
specified with the <b><a href="postconf.5.html#mailbox_command_maps">mailbox_command_maps</a></b> and <b><a href="postconf.5.html#mailbox_command">mailbox_com</a>-</b>

ondary groups are not enabled; in case of delivery as
118
root, the command executes with the privileges of
119
<b><a href="postconf.5.html#default_privs">default_privs</a></b>).

<b><a href="postconf.5.html#mailbox_transport_maps">box_transport_maps</a></b> and <b><a href="postconf.5.html#mailbox_transport">mailbox_transport</a></b> configuration

parameters specify an optional message transport that is
125
to be used for all local recipients, regardless of whether
126
they are found in the UNIX passwd database. The <b><a href="postconf.5.html#fallback_transport_maps">fall</a>-</b>

<b><a href="postconf.5.html#fallback_transport_maps">back_transport_maps</a></b> and <b><a href="postconf.5.html#fallback_transport">fallback_transport</a></b> parameters

131
In the case of UNIX-style mailbox delivery, the <a href="local.8.html"><b>local</b>(8)</a>

daemon prepends a "<b>From</b> <i>sender time</i><b>_</b><i>stamp</i>" envelope header
133
to each message, prepends an <b>X-Original-To:</b> header with
134
the recipient address as given to Postfix, prepends an
135
optional <b>Delivered-To:</b> header with the final envelope
136
recipient address, prepends a <b>Return-Path:</b> header with the
137
envelope sender address, prepends a > character to lines
138
beginning with "<b>From</b> ", and appends an empty line. The
139
mailbox is locked for exclusive access while delivery is
140
in progress. In case of problems, an attempt is made to

In the case of <b>maildir</b> delivery, the local daemon prepends

The default per-user mailbox is a file in the UNIX mail spool directory

92
ending in <b>/</b> for <b>qmail</b>-compatible <b>maildir</b> delivery.

Alternatively, the per-user mailbox can be a file in the user's home
95
directory with a name specified via the <b><a href="postconf.5.html#home_mailbox">home_mailbox</a></b> configuration
96
parameter. Specify a relative path name. Specify a name ending in <b>/</b> for

Mailbox delivery can be delegated to an external command specified with
100
the <b><a href="postconf.5.html#mailbox_command_maps">mailbox_command_maps</a></b> and <b><a href="postconf.5.html#mailbox_command">mailbox_command</a></b> configuration parameters.
101
The command executes with the privileges of the recipient user (excep-
102

<b><a href="postconf.5.html#mailbox_transport">box_transport</a></b> configuration parameters specify an optional message

whether they are found in the UNIX passwd database. The <b><a href="postconf.5.html#fallback_transport_maps">fall</a>-</b>
110
<b><a href="postconf.5.html#fallback_transport_maps">back_transport_maps</a></b> and <b><a href="postconf.5.html#fallback_transport">fallback_transport</a></b> parameters specify an

114
In the case of UNIX-style mailbox delivery, the <a href="local.8.html"><b>local</b>(8)</a> daemon
115
prepends a "<b>From</b> <i>sender time</i><b>_</b><i>stamp</i>" envelope header to each message,

prepends an <b>X-Original-To:</b> header with the recipient address as given
117
to Postfix, prepends an optional <b>Delivered-To:</b> header with the final
