+ /Usage/:
+
+ @
+ list-remote-forwards [OPTIONS]
+ @
+
+ List all remote forwards for mail accounts stored in a SQL database.
+
+ A list of local domains is supplied to the program (more or less)
+ through the @--domain-query@ option. Any addresses which
+ forward to another address not contained in this list of local domains
+ is considered a remote forward. Remote forwards can cause problems for
+ a number of reasons, the most common of which are,
+
+ * If the sender has an SPF record authorizing his mail server to send
+ mail on his behalf, then when his message is forwarded by the
+ recipient's mail server, it will fail any subsequent SPF checks. This
+ will likely cause the message to be rejected, and the original
+ recipient's server will generate backscatter.
+
+ * If any spam makes it through the filter on the recipient's mail
+ server, that spam will then be forwarded to a remote destination. The
+ remote destination will blame the forwarding server for the spam, and
+ that can impact its reputation and potentially lead to a blacklisting
+ even though the spam did not originate on the recipient's server.
+
+ Whether or not these are an issue depends on the circumstances, but in
+ any case it is useful to know who is forwarding mail off-site.
+
+ /Input:/
+
+ None.
+
+ /Output:/
+
+ A list of addresses that are forwarded to remote domains.
+
+ /Options/:
+
+ @
+ \--database
+ @
+
+ The name of the database (or file, if SQLite) to which we should
+ connect.
+
+ Default: The name of the current user (Postgres only).
+
+ @
+ \--domain-query
+ @
+ SQL query used to produce a list of local domains. This should return
+ the set of all domains (i.e one column) that are local to the
+ server. See the default value for an example.
+
+ Default: \"SELECT domain FROM domain WHERE domain <> 'ALL' ORDER BY domain;\"
+
+ @
+ \--exclude-mx, -e
+ @
+
+ The name of a mail exchanger, the forwards of whose domains we should
+ ignore. For example, if one mail exchanger, mx1.example.com, has
+ strict spam filtering, it may be acceptable to have remote forwarding
+ for domains that have mx1.example.com as their sole mail exchanger (MX
+ record). In that case, you might want to exclude those domains from
+ the report by naming mx1.example.com here.
+
+ A forward will be excluded from the report only if /all/ of its MX
+ records are contained in the given exclude list.
+
+ This option can be repeated to add mail exchangers to the exclude list.
+
+ Default: [] (empty)
+
+ @
+ \--forward-query, -f
+ @
+
+ SQL query used to produce a list of all forwards on the mail
+ system. This query should return the set of all (address, goto)
+ triples, where \"goto\" is the destination address; i.e. to where
+ the \"address\" forwards. The \"goto\" field may contain more
+ than one email address, separated by commas.
+
+ Default: \"SELECT address,goto FROM alias ORDER BY address;\"
+
+ @
+ \--host, -h
+ @
+
+ Hostname where the database is located (Postgres-only).
+
+ Default: None, a UNIX domain socket connection is attempted (Postgres only)
+
+ @
+ \--password
+ @
+
+ Password used to connect to the database (Postgres-only).
+
+ Default: None (assumes passwordless authentication)
+
+ @
+ \--port
+ @
+ Port number used to connect to the database (Postgres-only).
+
+ Default: None, a UNIX domain socket connection is attempted (Postgres only)
+
+ @
+ \--username, -u
+ @
+
+ Username used to connect to the database (Postgres-only).
+
+ Default: The current user
+
+ /Examples/:
+
+ @
+ $ list-remote-forwards --database=test/fixtures/postfixadmin.sqlite3
+ user1@example.com -> user1@example.net
+ user2@example.com -> user1@example.org
+ user2@example.com -> user2@example.org
+ user2@example.com -> user3@example.org
+ user7@example.com -> user8@example.net
