+.SH DESCRIPTION
+.ad
+.fi
+The optional \fBgeneric\fR(5) table specifies an address
+mapping that applies when mail is delivered. This is the
+opposite of \fBcanonical\fR(5) mapping, which applies when
+mail is received.
+
+Typically, one would use the \fBgeneric\fR(5) table on a
+system that does not have a valid Internet domain name and
+that uses something like \fIlocaldomain.local\fR instead.
+The \fBgeneric\fR(5) table is then used by the \fBsmtp\fR(8)
+client to transform local mail addresses into valid Internet
+mail addresses when mail has to be sent across the Internet.
+See the EXAMPLE section at the end of this document.
+
+The \fBgeneric\fR(5) mapping affects both message header
+addresses (i.e. addresses that appear inside messages) and
+message envelope addresses (for example, the addresses that
+are used in SMTP protocol commands).
+
+Normally, the \fBgeneric\fR(5) table is specified as a
+text file that serves as input to the \fBpostmap\fR(1)
+command.  The result, an indexed file in \fBdbm\fR or
+\fBdb\fR format, is used for fast searching by the mail
+system. Execute the command "\fBpostmap /etc/postfix/generic\fR"
+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 regular\-expression
+map where patterns are given as regular expressions, or lookups
+can be directed to a 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".
+.SH "CASE FOLDING"
+.na
+.nf
+.ad
+.fi
+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.
+.SH "TABLE FORMAT"
+.na
+.nf
+.ad
+.fi
+The input format for the \fBpostmap\fR(1) command is as follows:
+.IP "\fIpattern result\fR"
+When \fIpattern\fR matches a mail address, replace it by the
+corresponding \fIresult\fR.
+.IP "blank lines and comments"
+Empty lines and whitespace\-only lines are ignored, as
+are lines whose first non\-whitespace character is a `#'.
+.IP "multi\-line text"
+A logical line starts with non\-whitespace text. A line that
+starts with whitespace continues a logical line.
+.SH "TABLE SEARCH ORDER"
+.na
+.nf
+.ad
+.fi
+With lookups from indexed files such as DB or DBM, or from networked
+tables such as NIS, LDAP or SQL, each \fIuser\fR@\fIdomain\fR
+query produces a sequence of query patterns as described below.
+
+Each query pattern is sent to each specified lookup table
+before trying the next query pattern, until a match is
+found.
+.IP "\fIuser\fR@\fIdomain address\fR"
+Replace \fIuser\fR@\fIdomain\fR by \fIaddress\fR. This form
+has the highest precedence.
+.IP "\fIuser address\fR"
+Replace \fIuser\fR@\fIsite\fR by \fIaddress\fR when \fIsite\fR is
+equal to $\fBmyorigin\fR, when \fIsite\fR is listed in
+$\fBmydestination\fR, or when it is listed in $\fBinet_interfaces\fR
+or $\fBproxy_interfaces\fR.
+.IP "@\fIdomain address\fR"
+Replace other addresses in \fIdomain\fR by \fIaddress\fR.
+This form has the lowest precedence.
+.SH "RESULT ADDRESS REWRITING"
+.na
+.nf
+.ad
+.fi
+The lookup result is subject to address rewriting:
+.IP \(bu
+When the result has the form @\fIotherdomain\fR, the
+result becomes the same \fIuser\fR in \fIotherdomain\fR.
+.IP \(bu
+When "\fBappend_at_myorigin=yes\fR", append "\fB@$myorigin\fR"
+to addresses without "@domain".
+.IP \(bu
+When "\fBappend_dot_mydomain=yes\fR", append
+"\fB.$mydomain\fR" to addresses without ".domain".
+.SH "ADDRESS EXTENSION"
+.na
+.nf
+.fi
+.ad
+When a mail address localpart contains the optional recipient delimiter
+(e.g., \fIuser+foo\fR@\fIdomain\fR), the lookup order becomes:
+\fIuser+foo\fR@\fIdomain\fR, \fIuser\fR@\fIdomain\fR, \fIuser+foo\fR,
+\fIuser\fR, and @\fIdomain\fR.
+
+The \fBpropagate_unmatched_extensions\fR parameter controls whether
+an unmatched address extension (\fI+foo\fR) is propagated to the
+result of table lookup.
+.SH "REGULAR EXPRESSION TABLES"
+.na
+.nf
+.ad
+.fi
+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 \fBregexp_table\fR(5)
+or \fBpcre_table\fR(5).
+
+Each pattern is a regular expression that is applied to the entire
+address being looked up. Thus, \fIuser@domain\fR mail addresses are not
+broken up into their \fIuser\fR and \fI@domain\fR constituent parts,
+nor is \fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR.
+
+Patterns are applied in the order as specified in the table, 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 \fB$1\fR, \fB$2\fR and so on.
+.SH "TCP-BASED TABLES"
+.na
+.nf
+.ad
+.fi
+This section describes how the table lookups change when lookups
+are directed to a TCP\-based server. For a description of the TCP
+client/server lookup protocol, see \fBtcp_table\fR(5).
+This feature is available in Postfix 2.5 and later.
+
+Each lookup operation uses the entire address once.  Thus,
+\fIuser@domain\fR mail addresses are not broken up into their
+\fIuser\fR and \fI@domain\fR constituent parts, nor is
+\fIuser+foo\fR broken up into \fIuser\fR and \fIfoo\fR.
+
+Results are the same as with indexed file lookups.
+.SH "EXAMPLE"
+.na
+.nf
+.ad
+.fi
+The following shows a generic mapping with an indexed file.
+When mail is sent to a remote host via SMTP, this replaces
+\fIhis@localdomain.local\fR by his ISP mail address, replaces
+\fIher@localdomain.local\fR by her ISP mail address, and
+replaces other local addresses by his ISP account, with
+an address extension of \fI+local\fR (this example assumes
+that the ISP supports "+" style address extensions).
+
+.na
+.nf
+/etc/postfix/main.cf:
+    smtp_generic_maps = hash:/etc/postfix/generic
+
+/etc/postfix/generic:
+    his@localdomain.local   hisaccount@hisisp.example
+    her@localdomain.local   heraccount@herisp.example
+    @localdomain.local      hisaccount+local@hisisp.example
+
+.ad
+.fi
+Execute the command "\fBpostmap /etc/postfix/generic\fR"
+whenever the table is changed.  Instead of \fBhash\fR, some
+systems use \fBdbm\fR database files. To find out what
+tables your system supports use the command "\fBpostconf
+\-m\fR".
+.SH BUGS
+.ad
+.fi
+The table format does not understand quoting conventions.
+.SH "CONFIGURATION PARAMETERS"
