## - 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## The following configuration options are no longer valid.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

## 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 s
|
||||
|
||||
## 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/simple
|
||||
|
||||
## 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 file:/etc/mail/domains
|
||||
|
||||
|
||||
## 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 /var/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/mail/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/mail/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/mail/opendkim/TrustedHosts
|
||||
|
||||
## Identifies a set "internal" hosts whose mail should be signed rather than verified.
|
||||
InternalHosts refile:/etc/mail/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.
