# RELOCATED(5)                                                      RELOCATED(5)
# 
# NAME
#        relocated - Postfix relocated table format
# 
# SYNOPSIS
#        postmap /etc/postfix/relocated
# 
# DESCRIPTION
#        The  optional  relocated(5) table provides the information
#        that is used in "user has moved  to  new_location"  bounce
#        messages.
# 
#        Normally,  the  relocated(5)  table is specified as a text
#        file that serves as input to  the  postmap(1)  command  to
#        create an indexed file for fast lookup.
# 
#        Execute  the  command  "postmap /etc/postfix/relocated" to
#        rebuild a default-type indexed  file  after  changing  the
#        text  file,  or  execute  "postmap type:/etc/postfix/relo-
#        cated" to specify an explicit type.
# 
#        The default indexed  file  type  is  configured  with  the
#        default_database_type parameter. Depending on the platform
#        this may be one of lmdb:, cdb:, hash:,  or  dbm:  (without
#        the trailing ':').
# 
#        When  the  table  is provided via other means such as NIS,
#        LDAP or SQL, the same lookups are  done  as  for  ordinary
#        indexed  files.   Managing  such  databases is outside the
#        scope of Postfix.
# 
#        Alternatively, the  table  can  be  provided  as  a  regu-
#        lar-expression  map  where  patterns  are given as regular
#        expressions, or lookups can be  directed  to  a  TCP-based
#        server.  In those case, the lookups are done in a slightly
#        different way as described below under "REGULAR EXPRESSION
#        TABLES" or "TCP-BASED TABLES".
# 
#        Table lookups are case insensitive.
# 
# CASE FOLDING
#        The  search  string is folded to lowercase before database
#        lookup. As of Postfix 2.3, the search string is  not  case
#        folded  with database types such as regexp: or pcre: whose
#        lookup fields can match both upper and lower case.
# 
# TABLE FORMAT
#        o      By default, Postfix will prepend a hard-coded  pre-
#               fix  "5.1.6  User  has moved to " to a table lookup
#               result, and the format for a table entry is as fol-
#               lows:
# 
#                    pattern      new_location
# 
#               Where  new_location  specifies  contact information
#               such as an  email  address,  or  perhaps  a  street
#               address or telephone number.
# 
#        o      Postfix  3.11  and later can optionally disable the
#               hard-coded prefix. Specify "relocated_prefix_enable
#               =   no"  in  main.cf,  and  specify  relocated_maps
#               entries with your own RFC  3463-compliant  enhanced
#               status code and text, for example:
# 
#                    pattern      5.1.6 Mailbox has moved to user@example
#                    pattern      5.2.0 Mailbox is unavailable
#                    pattern      5.2.1 Mailbox is disabled
# 
#        o      Empty  lines and whitespace-only lines are ignored,
#               as are lines whose first  non-whitespace  character
#               is a `#'.
# 
#        o      A  logical  line starts with non-whitespace text. A
#               line that starts with whitespace continues a  logi-
#               cal line.
# 
# TABLE SEARCH ORDER
#        With lookups from indexed files such as DB or DBM, or from
#        networked tables such as NIS, LDAP or  SQL,  patterns  are
#        tried in the order as listed below:
# 
#        user@domain
#               Matches  user@domain. This form has precedence over
#               all other forms.
# 
#        user   Matches user@site when site is $myorigin, when site
#               is listed in $mydestination, or when site is listed
#               in $inet_interfaces or $proxy_interfaces.
# 
#        @domain
#               Matches other addresses in domain.  This  form  has
#               the lowest precedence.
# 
# ADDRESS EXTENSION
#        When a mail address localpart contains the optional recip-
#        ient delimiter (e.g., user+foo@domain), the  lookup  order
#        becomes: user+foo@domain, user@domain, user+foo, user, and
#        @domain.
# 
# REGULAR EXPRESSION TABLES
#        This section describes how the table lookups  change  when
#        the  table  is given in the form of regular expressions or
#        when lookups are directed to a  TCP-based  server.  For  a
#        description of regular expression lookup table syntax, see
#        regexp_table(5) or pcre_table(5). For a description of the
#        TCP client/server table lookup protocol, see tcp_table(5).
#        This feature is available in Postfix 2.5 and later.
# 
#        Each pattern is a regular expression that  is  applied  to
#        the entire address being looked up. Thus, user@domain mail
#        addresses are not broken up into their  user  and  @domain
#        constituent parts, nor is user+foo broken up into user and
#        foo.
# 
#        Patterns are applied in the order as specified in the  ta-
#        ble,  until  a  pattern  is  found that matches the search
#        string.
# 
#        Results are the same as with indexed  file  lookups,  with
#        the  additional feature that parenthesized substrings from
#        the pattern can be interpolated as $1, $2 and so on.
# 
# TCP-BASED TABLES
#        This section describes how the table lookups  change  when
#        lookups are directed to a TCP-based server. For a descrip-
#        tion of the TCP client/server lookup protocol, see tcp_ta-
#        ble(5).   This  feature  is  available  in Postfix 2.5 and
#        later.
# 
#        Each lookup operation uses the entire address once.  Thus,
#        user@domain  mail  addresses  are not broken up into their
#        user and @domain constituent parts, nor is user+foo broken
#        up into user and foo.
# 
#        Results are the same as with indexed file lookups.
# 
# BUGS
#        The  table format does not understand quoting conventions.
#
