NAME

     proxsmtpd.conf — the configuration file for proxsmtpd(8)

DESCRIPTION

     proxsmtpd(8) reads a configuration file when starting up. The location of the file is
     dependent on how you compiled proxsmtp but it should usually be in either the
     /usr/local/etc/ or /etc/ directories. If proxsmtpd(8) does not find its configuration file
     it'll print a warning when it starts up along with the location it's expecting to find it
     in. You can also specify a different location for a config file by passing the -f argument
     to proxsmtpd(8)

     The settings are specified one per line. The setting names come first, followed by a colon
     and then the value. Comments start with the '#' character on a line of their own. Whitespace
     is ignored at the beginning of line, end of line and around the colons.

     A sample configuration file can be found in the doc/ directory of the proxsmtp distribution.

SETTINGS

     The various settings are as follows:

     FilterCommand
                 This is the command used to filter email through. If not specified then no
                 filtering will be done. Specify all the arguments the command needs as you would
                 on a command-line.

                 [ Default: no filtering ]

     FilterTimeout
                 The amount of time in seconds to wait for the FilterCommand to process email
                 data.

                 [ Default: 30 seconds ]

     FilterReject
                 The rejection message used when FilterType is set to 'reject'.

                 [ Default: 530 Email Rejected ]

     FilterType  When set to 'pipe' the email data is piped through the FilterCommand using
                 standard in and standard out. When set to 'file' the email data is saved to a
                 file and the file name is passed to the FilterCommand using the EMAIL
                 environment variable.

                 When set to 'reject' then email is immediately rejected using message defined by
                 the FilterReject option.

                 [ Default: pipe ]

     Header      A header to add to scanned messages. Put an empty value to suppress adding a
                 header. You can include the following special formatting characters in the
                 string to include special values:

                 %i Client IP Address

                 %l Local IP Address

                 %d Current Date

                 You can also include the standard \r or \n escapes.

                 [ Optional ]

     KeepAlives  On slow connections the server will sometimes timeout before proxsmtpd(8) is
                 finished filtering the file. This option sends NOOP's to the server to keep the
                 connection alive. Specify the number of seconds, or 0 to disable.

                 [ Default: 0 ]

     Listen      The address and port to listen for SMTP connections on. See syntax of addresses
                 below.

                 [ Default: port 10025 on all local IP addresses ]

     MaxConnections
                 Specifies the maximum number of connections to accept at once.

                 [ Default: 64 ]

     OutAddress  The address of the SMTP server to send email to once it's been scanned. See
                 syntax of addreses below.

                 [ Required ]

     Skip        Whether to skip certain kinds of connections or email from running through the
                 filter. Specify 'authenticated' to skip SMTP authenticated connections.

                 [ Optional ]

     TempDirectory
                 The directory to write temp files to.

                 [ Default: /tmp ]

     TimeOut     The number of seconds to wait while reading data from network connections.

                 [ Default: 180 seconds ]

     TransparentProxy
                 Setting this option to 'client' enables transparent proxy support, which allows
                 you to route all SMTP traffic that's going through a gateway through proxsmtp
                 which will then send it on to its final destination. This setup usually involves
                 firewall rules which redirect traffic to proxsmtp, and the setup varies from OS
                 to OS.

                 Specify 'full' to enable a true transparent proxy where neither the client or
                 server are aware of the proxy by way of the packet headers. This setup usually
                 involves routers to redirect traffic to proxsmtp, and the setup varies from OS
                 to OS.

                 [ Default: off ]

     User        The user to run as. If this option is specified then proxsmtpd(8) must be
                 started as root. It will then drop root privileges and run as the specified
                 user. The user can either be a name or a numerical user id.

                 [ Optional ]

     XClient     Send an XCLIENT command to the receiving server. This is useful for forwarding
                 client addresses and connection info to servers that support this feature.

                 [ Default: off ]

ADDRESSES

     Addresses can be specified in multiple formats:

     ·   Unix local addresses can be specified by specifying their full path.  (ie:
         '/var/run/socket').

     ·   IP addresses can be specified using dotted notation with a colon before the port number
         (ie: '127.0.0.1:3310').

     ·   IPv6 addresses are implemented but disabled. The code needs testing.
