+# ACCESS(5)                                                            ACCESS(5)
+# 
+# NAME
+#        access - Postfix SMTP server access table
+# 
+# SYNOPSIS
+#        postmap /etc/postfix/access
+# 
+#        postmap -q "string" /etc/postfix/access
+# 
+#        postmap -q - /etc/postfix/access <inputfile
+# 
+# DESCRIPTION
+#        This  document  describes  access  control  on remote SMTP
+#        client information: host  names,  network  addresses,  and
+#        envelope  sender or recipient addresses; it is implemented
+#        by the  Postfix  SMTP  server.   See  header_checks(5)  or
+#        body_checks(5)  for access control on the content of email
+#        messages.
+# 
+#        Normally, the access(5) table is specified as a text  file
+#        that  serves  as  input  to  the  postmap(1) command.  The
+#        result, an indexed file in dbm or db format, is  used  for
+#        fast  searching  by  the  mail system. Execute the command
+#        "postmap /etc/postfix/access" to rebuild an  indexed  file
+#        after changing the corresponding text file.
+# 
+#        When  the  table  is provided via other means such as NIS,
+#        LDAP or SQL, the same lookups are  done  as  for  ordinary
+#        indexed files.
+# 
+#        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 TCP-based
+#        server. In those cases, the lookups are done in a slightly
+#        different way as described below under "REGULAR EXPRESSION
+#        TABLES" or "TCP-BASED TABLES".
+# 
+# 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
+#        The input format for the postmap(1) command is as follows:
+# 
+#        pattern action
+#               When pattern matches a mail address, domain or host
+#               address, perform the corresponding action.
+# 
+#        blank lines and comments
+#               Empty  lines and whitespace-only lines are ignored,
+#               as are lines whose first  non-whitespace  character
+#               is a `#'.
+# 
+#        multi-line text
+#               A  logical  line starts with non-whitespace text. A
+#               line that starts with whitespace continues a  logi-
+#               cal line.
+# 
+# EMAIL ADDRESS PATTERNS
+#        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 the specified mail address.
+# 
+#        domain.tld
+#               Matches  domain.tld  as the domain part of an email
+#               address.
+# 
+#               The pattern domain.tld also matches subdomains, but
+#               only when the string smtpd_access_maps is listed in
+#               the Postfix  parent_domain_matches_subdomains  con-
+#               figuration setting.
+# 
+#        .domain.tld
+#               Matches subdomains of domain.tld, but only when the
+#               string smtpd_access_maps is not listed in the Post-
+#               fix  parent_domain_matches_subdomains configuration
+#               setting.
+# 
+#        user@  Matches all mail addresses with the specified  user
+#               part.
+# 
+#        Note:  lookup  of  the null sender address is not possible
+#        with some types of lookup table. By default, Postfix  uses
+#        <>  as  the  lookup  key  for such addresses. The value is
+#        specified with the smtpd_null_access_lookup_key  parameter
+#        in the Postfix main.cf file.
+# 
+# EMAIL 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, domain, user+foo@,
+#        and user@.
+# 
+# HOST NAME/ADDRESS PATTERNS
+#        With lookups from indexed files such as DB or DBM, or from
+#        networked  tables  such as NIS, LDAP or SQL, the following
+#        lookup patterns are examined in the order as listed:
+# 
+#        domain.tld
+#               Matches domain.tld.
+# 
+#               The pattern domain.tld also matches subdomains, but
+#               only when the string smtpd_access_maps is listed in
+#               the Postfix  parent_domain_matches_subdomains  con-
+#               figuration setting.
+# 
+#        .domain.tld
+#               Matches subdomains of domain.tld, but only when the
+#               string smtpd_access_maps is not listed in the Post-
+#               fix  parent_domain_matches_subdomains configuration
+#               setting.
+# 
+#        net.work.addr.ess
+# 
+#        net.work.addr
+# 
+#        net.work
+# 
+#        net    Matches a  remote  IPv4  host  address  or  network
+#               address  range.  Specify one to four decimal octets
+#               separated by ".". Do not specify "[]" , "/",  lead-
+#               ing zeros, or hexadecimal forms.
+# 
+#               Network ranges are matched by repeatedly truncating
+#               the last ".octet" from a remote IPv4  host  address
+#               string, until a match is found in the access table,
+#               or until further truncation is not possible.
+# 
+#               NOTE: use the cidr lookup  table  type  to  specify
+#               network/netmask  patterns.  See  cidr_table(5)  for
+#               details.
+# 
+#        net:work:addr:ess
+# 
+#        net:work:addr
+# 
+#        net:work
+# 
+#        net    Matches a  remote  IPv6  host  address  or  network
+#               address  range.  Specify three to eight hexadecimal
+#               octet pairs separated by ":", using the  compressed
+#               form  "::"  for  a  sequence  of  zero-valued octet
+#               pairs. Do not specify "[]", "/", leading zeros,  or
+#               non-compressed forms.
+# 
+#               A network range is matched by repeatedly truncating
+#               the  last  ":octetpair"  from  the  compressed-form
+#               remote  IPv6  host address string, until a match is
+#               found in the access table, or until further trunca-
+#               tion is not possible.
+# 
+#               NOTE:  use  the  cidr  lookup table type to specify
+#               network/netmask  patterns.  See  cidr_table(5)  for
+#               details.
+# 
+#               IPv6 support is available in Postfix 2.2 and later.
+# 
+# ACCEPT ACTIONS
+#        OK     Accept the address etc. that matches the pattern.
+# 
+#        all-numerical
+#               An all-numerical result is treated as OK. This for-
+#               mat  is generated by address-based relay authoriza-
+#               tion schemes such as pop-before-smtp.
+# 
+#        For other accept actions, see "OTHER ACTIONS" below.
+# 
+# REJECT ACTIONS
+#        Postfix version 2.3  and  later  support  enhanced  status
+#        codes  as  defined in RFC 3463.  When no code is specified
+#        at the beginning of the  text  below,  Postfix  inserts  a
+#        default  enhanced  status  code  of "5.7.1" in the case of
+#        reject actions, and "4.7.1" in the case of defer  actions.
+#        See "ENHANCED STATUS CODES" below.
+# 
+#        4NN text
+# 
+#        5NN text
+#               Reject  the  address etc. that matches the pattern,
+#               and respond with the numerical three-digit code and
+#               text.  4NN means "try again later", while 5NN means
+#               "do not try again".
+# 
+#               The following responses have  special  meaning  for
+#               the Postfix SMTP server:
+# 
+#               421 text (Postfix 2.3 and later)
+# 
+#               521 text (Postfix 2.6 and later)
+#                      After    responding   with   the   numerical
+#                      three-digit code and text, disconnect  imme-
+#                      diately from the SMTP client.  This frees up
+#                      SMTP server resources so that  they  can  be
+#                      made available to another SMTP client.
+# 
+#                      Note: The "521" response should be used only
+#                      with botnets and other malware where  inter-
+#                      operability is of no concern.  The "send 521
+#                      and disconnect" behavior is NOT  defined  in
+#                      the SMTP standard.
+# 
+#        REJECT optional text...
+#               Reject  the  address etc. that matches the pattern.
+#               Reply   with   "$access_map_reject_code    optional
+#               text..."  when the optional text is specified, oth-
+#               erwise reply with a generic error response message.
+# 
+#        DEFER optional text...
+#               Reject  the  address etc. that matches the pattern.
+#               Reply   with    "$access_map_defer_code    optional
+#               text..."  when the optional text is specified, oth-
+#               erwise reply with a generic error response message.
+# 
+#               This feature is available in Postfix 2.6 and later.
+# 
+#        DEFER_IF_REJECT optional text...
+#               Defer the request if some later  restriction  would
+#               result    in    a   REJECT   action.   Reply   with
+#               "$access_map_defer_code  4.7.1  optional   text..."
+#               when  the  optional  text  is  specified, otherwise
+#               reply with a generic error response message.
+# 
+#               Prior to Postfix 2.6, the SMTP reply code is 450.
+# 
+#               This feature is available in Postfix 2.1 and later.
+# 
+#        DEFER_IF_PERMIT optional text...
+#               Defer  the  request if some later restriction would
+#               result in a an explicit or implicit PERMIT  action.
+#               Reply  with "$access_map_defer_code 4.7.1  optional
+#               text..." when the optional text is specified,  oth-
+#               erwise reply with a generic error response message.
+# 
+#               Prior to Postfix 2.6, the SMTP reply code is 450.
+# 
+#               This feature is available in Postfix 2.1 and later.
+# 
+#        For other reject actions, see "OTHER ACTIONS" below.
+# 
+# OTHER ACTIONS
+#        restriction...
+#               Apply the named UCE restriction(s) (permit, reject,
+#               reject_unauth_destination, and so on).
+# 
+#        BCC user@domain
+#               Send one copy  of  the  message  to  the  specified
+#               recipient.
+# 
+#               If  multiple  BCC  actions are specified within the
+#               same SMTP MAIL transaction, with Postfix  3.0  only
+#               the last action will be used.
+# 
+#               This feature is available in Postfix 3.0 and later.
+# 
+#        DISCARD optional text...
+#               Claim successful delivery and silently discard  the
+#               message.   Log the optional text if specified, oth-
+#               erwise log a generic message.
+# 
+#               Note: this action currently affects all  recipients
+#               of  the  message.   To  discard  only one recipient
+#               without discarding  the  entire  message,  use  the
+#               transport(5) table to direct mail to the discard(8)
+#               service.
+# 
+#               This feature is available in Postfix 2.0 and later.
+# 
+#        DUNNO  Pretend  that  the  lookup  key was not found. This
+#               prevents Postfix  from  trying  substrings  of  the
+#               lookup  key (such as a subdomain name, or a network
+#               address subnetwork).
+# 
+#               This feature is available in Postfix 2.0 and later.
+# 
+#        FILTER transport:destination
+#               After  the  message is queued, send the entire mes-
+#               sage through the specified external content filter.
+#               The  transport  name specifies the first field of a
+#               mail delivery agent definition  in  master.cf;  the
+#               syntax  of the next-hop destination is described in
+#               the  manual  page  of  the  corresponding  delivery
+#               agent.   More  information  about  external content
+#               filters is in the Postfix FILTER_README file.
+# 
+#               Note 1: do not use $number regular expression  sub-
+#               stitutions  for transport or destination unless you
+#               know that the information has a trusted origin.
+# 
+#               Note 2: this  action  overrides  the  main.cf  con-
+#               tent_filter  setting, and affects all recipients of
+#               the message.  In  the  case  that  multiple  FILTER
+#               actions fire, only the last one is executed.
+# 
+#               Note  3:  the  purpose  of the FILTER command is to
+#               override message routing.  To override the  recipi-
+#               ent's  transport  but not the next-hop destination,
+#               specify an empty filter  destination  (Postfix  2.7
+#               and later), or specify a transport:destination that
+#               delivers  through  a  different  Postfix   instance
+#               (Postfix  2.6 and earlier). Other options are using
+#               the recipient-dependent transport_maps or the  sen-
+#               der-dependent   sender_dependent_default_transport-
+#               _maps features.
+# 
+#               This feature is available in Postfix 2.0 and later.
+# 
+#        HOLD optional text...
+#               Place  the message on the hold queue, where it will
+#               sit until someone either deletes it or releases  it
+#               for  delivery.  Log the optional text if specified,
+#               otherwise log a generic message.
+# 
+#               Mail that is placed on hold can  be  examined  with
+#               the  postcat(1)  command,  and  can be destroyed or
+#               released with the postsuper(1) command.
+# 
+#               Note: use "postsuper -r" to release mail  that  was
+#               kept  on  hold for a significant fraction of $maxi-
+#               mal_queue_lifetime  or  $bounce_queue_lifetime,  or
+#               longer.  Use "postsuper -H" only for mail that will
+#               not expire within a few delivery attempts.
+# 
+#               Note: this action currently affects all  recipients
+#               of the message.
+# 
+#               This feature is available in Postfix 2.0 and later.
+# 
+#        PREPEND headername: headervalue
+#               Prepend the specified message header  to  the  mes-
+#               sage.   When more than one PREPEND action executes,
+#               the first prepended header appears before the  sec-
+#               ond etc. prepended header.
+# 
+#               Note:  this  action must execute before the message
+#               content is received; it cannot execute in the  con-
+#               text of smtpd_end_of_data_restrictions.
+# 
+#               This feature is available in Postfix 2.1 and later.
+# 
+#        REDIRECT user@domain
+#               After the message is queued, send  the  message  to
+#               the  specified  address  instead  of  the  intended
+#               recipient(s).  When multiple REDIRECT actions fire,
+#               only the last one takes effect.
+# 
+#               Note:  this action overrides the FILTER action, and
+#               currently overrides all recipients of the  message.
+# 
+#               This feature is available in Postfix 2.1 and later.
+# 
+#        INFO optional text...
+#               Log an informational record with the optional text,
+#               together  with client information and if available,
+#               with helo, sender, recipient and protocol  informa-
+#               tion.
+# 
+#               This feature is available in Postfix 3.0 and later.
+# 
+#        WARN optional text...
+#               Log a warning with the optional text, together with
+#               client  information  and  if  available, with helo,
+#               sender, recipient and protocol information.
+# 
+#               This feature is available in Postfix 2.1 and later.
+# 
+# ENHANCED STATUS CODES
+#        Postfix  version  2.3  and  later  support enhanced status
+#        codes as defined in RFC 3463.   When  an  enhanced  status
+#        code  is  specified  in  an access table, it is subject to
+#        modification. The  following  transformations  are  needed
+#        when  the  same  access  table  is  used for client, helo,
+#        sender, or  recipient  access  restrictions;  they  happen
+#        regardless of whether Postfix replies to a MAIL FROM, RCPT
+#        TO or other SMTP command.
+# 
+#        o      When a sender address matches a REJECT action,  the
+#               Postfix  SMTP server will transform a recipient DSN
+#               status (e.g., 4.1.1-4.1.6) into  the  corresponding
+#               sender DSN status, and vice versa.
+# 
+#        o      When   non-address  information  matches  a  REJECT
+#               action (such as the HELO command  argument  or  the
+#               client  hostname/address),  the Postfix SMTP server
+#               will transform a sender  or  recipient  DSN  status
+#               into   a  generic  non-address  DSN  status  (e.g.,
+#               4.0.0).

+# REGULAR EXPRESSION TABLES
+#        This section describes how the table lookups  change  when
+#        the table is given in the form of regular expressions. For
+#        a description of regular expression lookup  table  syntax,
+#        see regexp_table(5) or pcre_table(5).
+# 
+#        Each  pattern  is  a regular expression that is applied to
+#        the entire string being looked up. Depending on the appli-
+#        cation,  that  string  is  an  entire  client hostname, an
+#        entire client IP address, or an entire mail address. Thus,
+#        no  parent  domain  or  parent  network  search  is  done,
+#        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.
+# 
+#        Actions 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 not available up to and including
+#        Postfix version 2.4.
+# 
+#        Each lookup operation uses the entire query  string  once.
+#        Depending  on  the  application,  that string is an entire
+#        client hostname, an entire client IP address, or an entire
+#        mail  address.   Thus,  no parent domain or parent network
+#        search is done, 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.
+# 
+#        Actions are the same as with indexed file lookups.
+# 
+# EXAMPLE
+#        The following example uses an indexed file,  so  that  the
+#        order  of  table entries does not matter. The example per-
+#        mits access by the client at address 1.2.3.4  but  rejects
+#        all  other  clients  in 1.2.3.0/24. Instead of hash lookup
+#        tables, some systems use dbm.  Use the  command  "postconf
+#        -m"  to  find  out  what lookup tables Postfix supports on
+#        your system.
+# 
+#        /etc/postfix/main.cf:
+#            smtpd_client_restrictions =
+#                check_client_access hash:/etc/postfix/access
+# 
+#        /etc/postfix/access:
+#            1.2.3   REJECT
+#            1.2.3.4 OK
+# 
+#        Execute the command  "postmap  /etc/postfix/access"  after
+#        editing the file.
+# 
+# BUGS
+#        The  table format does not understand quoting conventions.
