Jules,
Are you going to update the 'MailScanner -V' output to check for these
requirements too?
Cheers,

I have updated my ClamAV+SpamAssassin package to SpamAssassin 3.3.0.
I have added all the new requirements to it, of which there are quite a
few (requirements have their own requirements, etc...). I have also
improved the installation script a bit for you too.
Please do download it from here:
http://www.mailscanner.info/files/4/install-Clam-SA-latest.tar.gz
and try it out for me!
Cheers folks,
Jules.

> - the 'exists:' evaluator in HEADER rules now works as documented
> and tests for existence of a header field, instead of testing for
> a header field body being nonempty; internally, the pms->get can
> also now distinguish between empty and nonexistent header fields;
>
> - applied fixes to header fields parsing in several places: header
field
> names are case-insensitive, whitespace is not required after a
colon,
> obsolete rfc822 syntax allowed whitespace before a colon;
> VBounce: match "Received:" only at the beginning of a line;
>
> - fixed bugs 6237 and 6295: 1.0.0.0/8 and 2.0.0.0/8 are now valid
> allocated
> address ranges, fixed a corresponding rule RCVD_ILLEGAL_IP;
>
> - fixed bug 6205 comment 5 in URIDetail.pm;
>
> - 'pyzor_options' in Plugin/Pyzor.pm was not untainted;
>
> - made the URIDetail plugin taint safe;
>
> - fixed parsing of multi-line Received header fields for
> BOUNCE_MESSAGE/VBOUNCE_MESSAGE et al;
>
> - Bug 6206, Bug 2536: spamd: untaint directory as obtained from a
> password
> file or from vpopmail utilities, avoid implicit untainting; report

> if user preferences file exists but cannot be accessed;
>
> - avoided using raw data from DNS as a regexp in Plugin/ASN.pm;
>
> - ensured the dbg() and info() calls always return the same value
(true)
> regardless of log level;
>
> - suppressed logging of $& when its value is not available (i.e. when
> no regexp has been evaluated during rule evaluation);
>
> - Exporter never really worked in SA, was not enclosed in BEGIN {};
>
> - masses/runGA and masses/mk-baseline-results: prevent a shell
'source'
> command from loading an unrelated file named 'config' which happens
> to be
> in the current PATH - must use a ./ in an arg to a 'source'
> command;
>
>
> ERROR HANDLING, ROBUSTNESS
>
> - improved error detection and reporting: test status of all system
> calls
> and I/O operations (or explicitly document where not), and report
> unexpected failures;
>
> - eval calls now check for eval result instead of testing the $@,
which
> is not always reliable;
>
> - localized $@ and $! in DESTROY methods to prevent potential calls to
> eval
> and calls to system routines in code executed from a DESTROY method
> from clobbering global variables $@ and $!;
>
> - Util::helper_app_pipe_open_unix: contain a failing exec with an eval
> to prevent additional cases of process cloning. The exec could fail
> this way when given tainted arguments;
>
> - Util::helper_app_pipe_open_unix: flush stdout and stderr before
> forking,
> otherwise an error reported by exec (such as 'insecure dependency')
> was lost in a buffer;
>
> - eval-protected an open($fh,'-|') to capture implied fork failures
> due to lack of system resource;
>
> - explicit untainting: combine "use re 'taint'" with untaint_var(),
> avoiding implicit perl untainting, along with workarounds to
> prevent it;
>
> - added 'use strict' where missing;
>
> - avoided a bunch of warnings on "Use of uninitialized value";
>
> - clearly report reasons for helper application process failures;
>
> - t/SATest.pm: provide information about the process failure reason
> if a system() call fails; improved its reporting of failures;
>
> - improved error reporting in Plugin/DCC.pm on finding a DCC home
> directory
> to facilitate troubleshooting;
>
>
> OTHER CHANGES
>
> - pseudoheader "ALL:raw" returns a pristine header section,
> and pseudoheader "ALL" returns a cleaned header section
>
> - total rewrite of URI detection in plain text body;
>
> - many updates to the list of top level domains;
>
> - added 'util_rb_3tld', allowing 3-level TLDs to be listed in URIBLs
and
> allowing new 3TLDs to be added from rule updates;
>
> - avoided trusted_networks bog down due to O(n^2) loop with millions
> of entries;
>
> - applied fixes to Plugin/VBounce.pm, updated VBounce ruleset;
>
> - added support for a 'Communigate Pro' Received header field;
>
> - parse Communigate Pro "with HTTPU" auth token;
>
> - let DependencyInfo.pm understand a concept of recommended module
> version,
> besides a required version;
>
> - provided a workaround for Net::DNS::Packet::new inconsistency;
>
> - let SpamAssassin use either Digest::SHA or Digest::SHA1, whichever
is
> available (the Digest::SHA is now a base module since perl 5.10.0);
>
> - improved parsing of eval-type rules: allow unquoted domain names as
> arguments, disallow unmatched quotes;
>
> - provided a new module Mail::SpamAssassin::BayesStore::BDB. It should
> be
> treated as alpha-quality (needs more testing) and is not yet ready
for
> production use;
>
> - exposed existing function 'received_within_months' as an eval
function
> in Plugin/HeaderEval.pm;
>
> - moved rc script to /var/lock/subsys/spamd instead of
> /var/lock/subsys/spamassassin so 'service spamd status' will work;
>
> - added feature to re-download MIRRRORED.BY files at least once a
> week, or if
> 'sa-update --refreshmirrors' switch is used;
>
> - input delimiter $/ can be corrupted by a plugin, localize $/ and $\
> before
> calling a plugin;
>
> - bumped the retry counter to 180 seconds for starting spamd on slow
> machines;
>
> - resolved Bug 5325: syslog severity level in spamc/libspamc.c for max
> message size (changed LOG_ERR into LOG_NOTICE for the message:
> "skipped message, greater than max message size");
>
> - added checker to avoid taint warnings if hostname is returned as
> '(none)';
>
> - altered sa-update to produce an error message if a channel doesn't
> exist;
>
> - Bug 6150, Bug 6127, Bug 5981, Bug 5950, Bug 6191: let spamd
log/report
> a child process exit status or aborting condition in an informative
> way;
>
> - added checker to detect accidental match-everything regexps in
> rules;
>
> - updated garescorer for 3.3.0: use more epochs in GA runs for better
> scores;
> clarify some mass-check warning output, ensure rule name always
> appears at
> start of line; if a rule had no default/existing score in
> 50_scores.cf,
> don't tell the GA that 1.0 is an appropriate default value, instead
> pick
> the midway point of its score range. this produces better results;
> remove some dead code from masses/score-ranges-from-freqs;
>
> - set garescorer.c to report performance as iterations per second;
>
> - added test to ensure that all config settings are correctly handled
> when
> switching between users; added more config setting type metadata to
> enable
> those tests to work; and fix URIDetail to store config on the
> {conf} object,
> not on the plugin;
>
> - moved 'release tests' to xt/ directory; mirror long-running,
> net-tests and
> stress tests with xt/50_testname.t scripts to enforce their run
> before a
> release;
>
> - made numerous additional and updated self-tests;
>
> - added a Test::Perl::Critic release-test;
>
> - cleaned up some code based on suggestions by perl module
> Test::Perl::Critic,
> among others:
> . enable TestingAndDebugging::ProhibitNoStrict test but allow the
> use of 'no strict "refs"';
> . deal with BuiltinFunctions::RequireGlobFunction;
> . deal with ControlStructures::ProhibitMutatingListFunctions
> removing this exception from xt/60_perlcritic.t;
> . deal with BayesStore/BDB.pm,
> Variables::ProhibitConditionalDeclarations
> . now that the module Time::HiRes is a required module, we can
afford
> to replace a select() with Time::HiRes::sleep, and remove
exception
> BuiltinFunctions::ProhibitSleepViaSelect from xt/60_perlcritic.t;
>
> - updated documentation, fixing numerous typos and mistakes in
> documentation
> text and in log messages;
>
> - extensively improved development process:
> . automated testing through Hudson, a continuous integration tool;
> . improved mass-check system and rules oversight;

> 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.
