view release on metacpan or search on metacpan
SPFout filter module:
* Use Mail::SPF instead of the old Mail::SPF::Query. Added new "spf_options"
option with options for Mail::SPF::Server.
* Use the IPv6-supporting Net::Address::IP::Local rather than the IPv4-only
Net::Address::IPv4::Local module for auto-discovery of the local system's
outbound IP addresses. Note that auto-discovery does not work from behind
NATs, in which case outbound IP addresses must be configured manually using
the "outbound_ip_addresses" option.
+ 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:
+ Added for matching implausible and malformed date header fields.
SendCopy filter module:
+ Added for sending message copies to additional recipients.
Debian:
+ Automatically start and stop courier-filter-perl using Courier's
`filterctl` post-installation and pre-removal, respectively.
! "courier-filter-perl.conf" (previously "pureperlfilter.conf") config file
is no longer a conffile managed by dpkg. Migrate seamlessly.
! Install courier-filter-perl executable into /usr/lib/courier/filters/
rather than /usr/lib/.

Courier::Filter:
* If socket already exists, check whether it is dead or alive. If it is
dead, remove it and start up normally. If it is alive, die like before.
(Closes: Debian #326785)
* Ignore connections that don't send any data.
Courier::Message:
* Decode header text as "UTF-8" encoded, not as "utf8" encoded. Starting
with Perl 5.8.7, this does make a difference. "utf8" allows invalid
Unicode codepoints (such as UTF-16 surrogates), while "UTF-8" (the official
standard UTF-8) doesn't. We want to avoid invalid codepoints because they
tend to cause trouble later.
* Don't die on invalid characters in encoded-word chunks. If an encoded-word
cannot be decoded, retain it undecoded.
* "authenticated" property: refined parsing of "Received:" header and "AUTH:"
authentication information.
+ Added "authenticated_user" property.
* Corrected documentation of "header" property.
SPFout filter module:
* Don't be pedantic about what our "public" IPv4 address is vis-Ã -vis the
various recipient MXes. Assume we just have a single public address that
applies to all recipient MXes. (Let's see if anyone out there actually has
a more complex setup...)
Parts filter module:
* Requires IO::InnerFile 2.110 or later, Archive::Zip.
SpamAssassin filter module:
+ Added for SpamAssassin-based spam detection.
! Requires Mail::SpamAssassin.
Miscellaneous:
* Relaxed sender IPv4 address matching in DNSBL, SPF, and SPFout filter
modules, making the "::ffff:" IPv6 prefix optional and thus supporting
IPv6-disabled versions of Courier.
* Courier::Filter::Overview: Updated mention of pythonfilter from version 0.5
to 0.8.
* README: Added license statement.
+ INSTALL: Added system requirements and building/installation instructions.
* Minor documentation fixes.
Debian:
* Recommends: libmime-perl, not libmime-tools-perl. (Closes: Debian #297730)
! Recommends: libio-stringy-perl (>= 2.110), libmail-spamassassin-perl,
libarchive-zip-perl.
--- 0.16 (2005-01-17 19:11)
Debian:
* Explicitly specify the dependency on Perl 5.8 so upgrades from Woody are
guaranteed to work smoothly and also to simplify backporting. This deals
with Debian bug #289796.
! Recommend libnet-dns-perl. Suggest libnet-rblclient-perl,
libnet-address-ipv4-local-perl, and libclamav-client-perl (all of which are
not yet packaged for Debian).
SPF filter module:
! Deprecated the "reject_on" option in favor of the new "match_on" option.
! Removed "none" from the default set of result codes to match on.
! Changed the documentation to recommend also rejecting on "unknown" results.
+ Added a reference in the documentation to the spf-draft-200406
specification, to which this module complies.
