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 ]

     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.

                 [ 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 ]

     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
                 This option 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.

                 [ 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.
