/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
