| Subject: ANNOUNCE: Apache SpamAssassin 3.4.1-rc2 available |
| |
| Release Notes -- Apache SpamAssassin -- Version 3.4.1-rc2 |
| |
| Introduction |
| ------------ |
| |
| Apache SpamAssassin 3.4.1 represents more than a year of development and |
| nearly 500 tweaks, changes, upgrades and bug fixes over the previous release. |
| Highlights include: Improved automation to help combat spammers that are |
| abusing new top level domains; Tweaks to the SPF support to block more spoofed |
| emails; Increased character set normalization to make rules easier to develop, |
| block more international spam & stop spammers from using alternate character |
| sets to bypass tests; Continued refinement to the native IPv6 support; and |
| Improved Bayesian classification with better debugging and attachment hashing. |
| |
| Notable features: |
| ================= |
| |
| Bug 7115: Adding SHA digests of MIME parts as Bayes tokens allows bayes |
| to see non-textual content - added configurability |
| |
| rewritten Node::_normalize |
| |
| improved tokenization of UTF-8 -encoded or normalized text in |
| the Bayes plugin |
| |
| |
| New configuration options |
| ------------------------- |
| |
| Added flag 'noawl' to the 'tflags' configuration option. |
| |
| |
| parse_dkim_uris ( 0 | 1 ) (default: 0) |
| |
| If this option is set to 1 and the message contains DKIM headers, |
| the headers will be parsed for URIs to process alongside URIs found |
| in the body with some rules and moduels (ex. URIDNSBL) |
| |
| |
| perl_version |
| (Introduced in 3.4.2) This will be replaced with the version |
| -->> THIS NEEDS TO BE FIXED in Conf.pm, WE ARE AT 3.4.1 |
| |
| |
| changed implementation, may produce different result in some cases: |
| |
| normalize_charset ( 0 | 1) (default: 0) |
| Whether to decode non- UTF-8 and non-ASCII textual parts and recode |
| them to UTF-8 before the text is given over to rules processing. |
| The character set used for attempted decoding is primarily based on |
| a declared character set in a Content-Type header, but if the |
| decoding attempt fails a module Encode::Detect::Detector is |
| consulted (if available) to provide a guess based on the actual |
| text, and decoding is re-attempted. Even if the option is enabled |
| no unnecessary decoding and re-encoding work is done when possible |
| (like with an all-ASCII text with a US-ASCII or extended ASCII |
| character set declaration, e.g. UTF-8 or ISO-8859-nn or Windows-nnnn). |
| |
| Unicode support in old versions of perl or in a core module Encode |
| is likely to be buggy in places, so if the normalize_charset |
| function is enabled it is advised to stick to more recent versions |
| of perl (preferably 5.12 or later). The module |
| Encode::Detect::Detector is optional, when necessary it will be |
| used if it is available. |
| |
| |
| option dns_server can now specify a link-local IPv6 address, e.g.: |
| dns_server [fe80::1%lo0]:53 |
| |
| |
| new option: |
| |
| bayes_token_sources (default: header visible invisible uri) |
| Controls which sources in a mail message can contribute tokens |
| (e.g. words, phrases, etc.) to a Bayes classifier. The argument is |
| a space-separated list of keywords: header, visible, invisible, |
| uri, mimepart), each of which may be prefixed by a no to indicate |
| its exclusion. Additionally two reserved keywords are allowed: all |
| and none (or: noall). The list of keywords is processed |
| sequentially: a keyword all adds all available keywords to a set |
| being built, a none or noall clears the set, other non-negated |
| keywords are added to the set, and negated keywords are removed |
| from the set. Keywords are case-insensitive. |
| |
| The default set is: header visible invisible uri, which is |
| equivalent for example to: All NoMIMEpart. The reason why mimepart |
| is not currently in a default set is that it is a newer source |
| (introduced with SpamAssassin version 3.4.1) and not much |
| experience has yet been gathered regarding its usefulness. |
| |
| See also option "bayes_ignore_header" for a fine-grained control on |
| individual header fields under the umbrella of a more general |
| keyword header here. |
| |
| Keywords imply the following data sources: |
| header - tokens collected from a message header section |
| visible - words from visible text (plain or HTML) in a message body |
| invisible - hidden/invisible text in HTML parts of a message body |
| uri - URIs collected from a message body |
| mimepart - digests (hashes) of all MIME parts (textual or non- |
| textual) of a message, computed after Base64 and quoted-printable |
| decoding, suffixed by their Content-Type |
| all - adds all the above keywords to the set being assembled |
| none or noall - removes all keywords from the set |
| |
| The "bayes_token_sources" directive may appear multiple times, its |
| keywords are interpreted sequentially, adding or removing items |
| from the final set as they appear in their order in |
| "bayes_token_sources" directive(s). |
| |
| |
| new option: |
| |
| dkim_minimum_key_bits n (default: 1024) |
| The smallest size of a signing key (in bits) for a valid signature |
| to be considered for whitelisting. Additionally, the eval function |
| check_dkim_valid() will return false on short keys when called with |
| explicitly listed domains, and the eval function |
| check_dkim_valid_author_sig() will return false on short keys |
| (regardless of its arguments). Setting the option to 0 disables a |
| key size check. |
| |
| Note that the option has no effect when the eval function |
| check_dkim_valid() is called with no arguments (like in a rule |
| DKIM_VALID). A mere presence of some valid signature on a message |
| has no reputational value (without being associated with a |
| particular domain), regardless of its key size - anyone can prepend |
| its own signature on a copy of some third party mail and re-send |
| it, which makes it no more trustworthy than without such signature. |
| This is also a reason for a rule DKIM_VALID to have a near-zero score. |
| |
| |
| change: |
| |
| check_rbl_from_domain |
| This checks all the from addrs domain names as an alternate to |
| check_rbl_from_host. As of v3.4.1, it has been improved to include |
| a subtest for a specific octet. |
| |
| |
| new template tags: |
| _SENDERDOMAIN_ a domain name of the envelope sender address, lowercased |
| _AUTHORDOMAIN_ a domain name of the author address (the From header |
| field), lowercased; note that RFC 5322 allows a mail |
| message to have multiple authors - currently only the |
| domain name of the first email address is returned |
| |
| INTERNAL: |
| new methods in Mail::SpamAssassin::PerMsgStatus : |
| |
| $pms->get_names_of_tests_hit_with_scores_hash |
| |
| After a mail message has been checked, this method can be called. |
| It will return a pointer to a hash for rule & score pairs for all |
| the symbolic test names and individual scores of the tests which |
| were triggered by the mail. |
| |
| $pms->get_names_of_tests_hit_with_scores |
| |
| After a mail message has been checked, this method can be called. |
| It will return a comma-separated string of rule=score pairs for all |
| the symbolic test names and individual scores of the tests which |
| were triggered by the mail. |
| |

| GPG Verification Procedure |
| -------------------------- |
| The release files also have a .asc accompanying them. The file serves |
| as an external GPG signature for the given release file. The signing |
| key is available via the wwwkeys.pgp.net key server, as well as |
| http://www.apache.org/dist/spamassassin/KEYS |
| |
| The key information is: |
| |
| pub 4096R/F7D39814 2009-12-02 |
| Key fingerprint = D809 9BC7 9E17 D7E4 9BC2 1E31 FDE5 2F40 F7D3 9814 |
| uid SpamAssassin Project Management Committee <private@spamassassin.apache.org> |
| uid SpamAssassin Signing Key (Code Signing Key, replacement for 1024D/265FA05B) <dev@spamassassin.apache.org> |
| sub 4096R/7B3265A5 2009-12-02 |
| |
| To verify a release file, download the file with the accompanying .asc file and run the following commands: |
| |
| gpg -v --keyserver wwwkeys.pgp.net --recv-key F7D39814 |
| gpg --verify Mail-SpamAssassin-3.4.0.tar.bz2.asc |
| gpg --fingerprint F7D39814 |
| |
| Then verify that the key matches the signature. |
| |
| Note that older versions of gnupg may not be able to complete the steps |
| above. Specifically, GnuPG v1.0.6, 1.0.7 & 1.2.6 failed while v1.4.11 |
| worked flawlessly. |
| |
| See http://www.apache.org/info/verification.html for more information |
| on verifying Apache releases. |

| About Apache SpamAssassin |
| ------------------------- |
| |
| Apache SpamAssassin is a mature, widely-deployed open source project |
| that serves as a mail filter to identify spam. SpamAssassin uses a |
| variety of mechanisms including mail header and text analysis, Bayesian |
| filtering, DNS blocklists, and collaborative filtering databases. In |
| addition, Apache SpamAssassin has a modular architecture that allows |
| other technologies to be quickly incorporated as an addition or as a |
| replacement for existing methods. |
| |
| Apache SpamAssassin typically runs on a server, classifies and labels |
| spam before it reaches your mailbox, while allowing other components of |
| a mail system to act on its results. |
| |
| Most of the Apache SpamAssassin is written in Perl, with heavily |
| traversed code paths carefully optimized. Benefits are portability, |
| robustness and facilitated maintenance. It can run on a wide variety of |
| POSIX platforms. |
| |
| The server and the Perl library feels at home on Unix and Linux |
| platforms, and reportedly also works on MS Windows systems under ActivePerl. |

| freely-available, collaboratively-developed Open Source projects. The |
| pragmatic Apache License enables individual and commercial users to |
| easily deploy Apache software; the Foundation's intellectual property |
| framework limits the legal exposure of its 2,500+ contributors. |
