INTRODUCTION
============
In the source code for this package may be one or more segments of code
that are disabled, as they are slated for future release (FFR). These
are generally unreleased or incomplete features, or can be new algorithms
for existing features. They are often untested and currently unsupported,
and generally formally become part of the released software in some future
revision. There may or may not be documentation for them outside of this
file. Use them at your own risk.
To enable an FFR in the source code, specify "--enable-featurename" when
executing "./configure". For example, to add the "widget" feature, you would
add "--enable-widget" when executing "./configure".
FEATURES
========
Feature Name Description
allsymbols By default, the build will attempt to create a libopendkim
that only exports symbols intended to be exported;
internal-only functions are not visible. This feature
exports those as well. This is intended only for running
library unit tests. (libopendkim)
bodylength_db Optionally query a local database of recipient addresses
to determine if an "l=" tag should be applied when
signing. (opendkim)
capture_unknown_errors
When dkim_eom() returns an unexpected error of some kind,
quarantine the message for further analysis. (opendkim)
codecoverage Enables generation of profiling code for all libraries,
programs and tests. When running the library tests,
produces a report about code coverage based on the available
code coverage tools (gprof, gcov or lcov). (all)
diffheaders When verification fails for a message for which a "z="
tag was provided, compare the received headers to the original
headers to look for possible munging. Requires the tre
library, available at http://laurikari.net/tre.
(opendkim, libopendkim)
dkim_reputation Add experimental support for querying an open DKIM reputation
service. The service's URL is http://www.dkim-reputation.org.
(opendkim, libopendkim)
dnsupgrade Maintain two libar instances, the second in TCP mode, in case
any UDP queries come back truncated. Not meaningful unless
libar is in use. (libopendkim)
identity_header Enable selection of an identity for signing based on the
value found in a particular header. (opendkim)
ldap_caching Adds code that ensures duplicate LDAP queries aren't sent
and local caching of LDAP replies is done. (opendkim)
parsetime Adds a utility function reporting the value of the Date:
header for easy comparison to signature timestamps in order
to detect messages in which those values wildly differ.
INCOMPLETE. (libopendkim)
redirect Option to redirect messages to a specific address on
verification or ADSP failure. (opendkim)
replace_rules Allow specification of a "replacement rules" table
for use when signing, replacing certain patterns in
address headers with specific strings to anticipate the
effects of the "masquerade" and "genericstable" features in
the MTA. (opendkim)
report_intervals
Support for report intervals, part of the DKIM reporting
extensions. (opendkim)
resign Experimental API features for simultaneous verifying and
re-signing of a single message. (libopendkim)
select_canonicalization
Optionally override the value of the "-c" command line flag
by specifying a preferred canonicalization on a special
header line. Intended mostly for testing, not production
use. (opendkim)
selector_header Enable selection of which selector (and thus which key)
to use when signing based on the contents of an arbitrary
header. (opendkim)
sender_macro Enable control over an MTA macro from which the address
of the sender is taken, rather than from header fields.
(opendkim)
stats Optional generation of statistics about pass/fail sorted
by domain and canonicalization. Requires Sleepycat DB.
(opendkim)
vbr Enable VBR (Vouch By Reference) header addition (outbound)
and processing (inbound). Under revision and may not be
stable. (opendkim)
ztags Save headers to a file for diagnostics when the signer used
a "z=" tag. (opendkim)
