CHANGES  view on Meta::CPAN

  + The switch to Mail::SPF and Net::Address::IP::Local brings IPv6 support!
  ! Deprecated the "unknown" and "error" SPF result codes in favor of the new
    "permerror" and "temperror" ones defined in RFC 4408.  The old result codes
    induce a warning when specified in the "match_on" option but are still
    supported for now.
  * Ignore messages with an empty identity of the configured scope (esp. empty
    MAIL FROM, i.e., bounces) or with an identity in the form of an IP address
    literal ("[<ip-address>]").

  SpamAssassin filter module:
  + Added a "prefs_file" option for easy configuration of Courier::Filter
    specific SpamAssassin preferences.  SpamAssassin now will not read any
    preferences besides its default configuration files unless this option is
    specified.
  * Eliminated memory leak by properly cleaning up Mail::SpamAssassin::Message
    objects.

  BlankBody filter module:
  + Added for matching blank message bodies (a stupid spammer symptom).

  FakeDate filter module:

=item B<new(%options)>: returns I<Courier::Filter::Module::SpamAssassin>

Creates a new B<SpamAssassin> filter module.

%options is a list of key/value pairs representing any of the following
options:

=over

=item B<prefs_file>

The path of a SpamAssassin preferences file.  If this option is specified, its
value is passed to L<< the Mail::SpamAssassin constructor's C<userprefs_filename>
option | Mail::SpamAssassin/userprefs_filename >>.  If B<undef>, SpamAssassin
is instructed not to read any preferences besides its default configuration
files.  Defaults to B<undef>.

=item B<sa_options>

A hash-ref specifying options for the Mail::SpamAssassin object used by this
filter module.  See L<Mail::SpamAssassin/new> for the supported options.

=back

All options of the B<Courier::Filter::Module> constructor are also supported.
Please see L<Courier::Filter::Module/new> for their descriptions.
