+## BASIC OPENDKIM CONFIGURATION FILE
+## See opendkim.conf(5) or /usr/share/doc/opendkim/opendkim.conf.sample for more
+
+## BEFORE running OpenDKIM you must:
+
+## - make your MTA (Postfix, Sendmail, etc.) aware of OpenDKIM
+## - generate keys for your domain (if signing)
+## - edit your DNS records to publish your public keys (if signing)
+
+## See /usr/share/doc/opendkim/INSTALL for detailed instructions.
+
+## DEPRECATED CONFIGURATION OPTIONS
+## 
+## The following configuration options are no longer valid.  They should be
+## removed from your existing configuration file to prevent potential issues.
+## Failure to do so may result in opendkim being unable to start.
+## 
+## Removed in 2.10.0:
+##   AddAllSignatureResults
+##   ADSPAction
+##   ADSPNoSuchDomain
+##   BogusPolicy
+##   DisableADSP
+##   LDAPSoftStart
+##   LocalADSP
+##   NoDiscardableMailTo
+##   On-PolicyError
+##   SendADSPReports
+##   UnprotectedPolicy
+
+## CONFIGURATION OPTIONS
+
+##  Specifies the path to the process ID file.
+PidFile	/var/run/opendkim/opendkim.pid
+
+##  Selects operating modes. Valid modes are s (sign) and v (verify). Default is v.
+##  Must be changed to s (sign only) or sv (sign and verify) in order to sign outgoing
+##  messages.
+Mode	v
+
+##  Log activity to the system log.
+Syslog	yes
+
+##  Log additional entries indicating successful signing or verification of messages.
+SyslogSuccess	yes
+
+##  If logging is enabled, include detailed logging about why or why not a message was
+##  signed or verified. This causes an increase in the amount of log data generated
+##  for each message, so set this to No (or comment it out) if it gets too noisy.
+LogWhy	yes
+
+##  Attempt to become the specified user before starting operations.
+UserID	opendkim:opendkim
+
+##  Create a socket through which your MTA can communicate.
+Socket	inet:8891@localhost
+
+##  Required to use local socket with MTAs that access the socket as a non-
+##  privileged user (e.g. Postfix)
+Umask	002
+
+##  This specifies a text file in which to store DKIM transaction statistics.
+##  OpenDKIM must be manually compiled with --enable-stats to enable this feature.
+# Statistics	/var/spool/opendkim/stats.dat
+
+##  Specifies whether or not the filter should generate report mail back
+##  to senders when verification fails and an address for such a purpose
+##  is provided. See opendkim.conf(5) for details.
+SendReports	yes
+
+##  Specifies the sending address to be used on From: headers of outgoing
+##  failure reports.  By default, the e-mail address of the user executing
+##  the filter is used (executing_user@hostname).
+# ReportAddress	"Example.com Postmaster" <postmaster@example.com>
+
+##  Add a DKIM-Filter header field to messages passing through this filter
+##  to identify messages it has processed.
+SoftwareHeader	yes
+
+## SIGNING OPTIONS
+
+##  Selects the canonicalization method(s) to be used when signing messages.
+Canonicalization	relaxed/relaxed
+
+##  Domain(s) whose mail should be signed by this filter. Mail from other domains will
+##  be verified rather than being signed. Uncomment and use your domain name.
+##  This parameter is not required if a SigningTable is in use.
+# Domain	example.com
+
+##  Defines the name of the selector to be used when signing messages.
+Selector	default
+
+##  Specifies the minimum number of key bits for acceptable keys and signatures.
+MinimumKeyBits	1024
+
+##  Gives the location of a private key to be used for signing ALL messages. This
+##  directive is ignored if KeyTable is enabled.
+KeyFile	/etc/opendkim/keys/default.private
+
+##  Gives the location of a file mapping key names to signing keys. In simple terms,
+##  this tells OpenDKIM where to find your keys. If present, overrides any KeyFile
+##  directive in the configuration file. Requires SigningTable be enabled.
+# KeyTable	/etc/opendkim/KeyTable
+
+##  Defines a table used to select one or more signatures to apply to a message based
+##  on the address found in the From: header field. In simple terms, this tells
+##  OpenDKIM how to use your keys. Requires KeyTable be enabled.
+# SigningTable	refile:/etc/opendkim/SigningTable
+
+##  Identifies a set of "external" hosts that may send mail through the server as one
+##  of the signing domains without credentials as such.
+# ExternalIgnoreList	refile:/etc/opendkim/TrustedHosts
+
+##  Identifies a set "internal" hosts whose mail should be signed rather than verified.
+InternalHosts	refile:/etc/opendkim/TrustedHosts
+
+##  Contains a list of IP addresses, CIDR blocks, hostnames or domain names
+##  whose mail should be neither signed nor verified by this filter.  See man
+##  page for file format.
+# PeerList	X.X.X.X
+
+##  Always oversign From (sign using actual From and a null From to prevent
+##  malicious signatures header fields (From and/or others) between the signer
+##  and the verifier.  From is oversigned by default in the Fedora package
+##  because it is often the identity key used by reputation systems and thus
+##  somewhat security sensitive.
+OversignHeaders	From
+
+##  Instructs the DKIM library to maintain its own local cache of keys and
+##  policies retrieved from DNS, rather than relying on the nameserver for
+##  caching service. Useful if the nameserver being used by the filter is
+##  not local.
+# QueryCache	yes
