SpamAssassin 3.2.0

[Randal, Phil]

The only thing which needs updating for a minimal install is Net::DNS up
a version or two from 0.57.

SA 3.2.0 will fall back to using Mail::SPF::Query if Mail::SPF is not
available.

However, I've been testing it with high volumes on an old Fedora Core 1
box and it's not happy - average message scan time is twice that of
3.1.8, and there's other weirdness.  One side effect is
MailScanner-mrtg's CPU load graph showing as zero when SA 3.2.0 is
struggling under load on this box (though the load averages aren't
higher than SA 3.1.8's under similar pressure).  I suspect something's
blocking when it shouldn't.

A mystery which I really don't have the time to investigate.

Cheers,

Phil

Julian, Some of those plugins ARE loaded by default, but are loaded via
older
.pre files. And yes, SA does parse *ALL* of the .pre files, and you need
to have
ALL of them to work properly.

The whole idea of the multiple .pre files is that as new plugins are
added, SA
doesn't have to do a config-merge. All it does is add the new .pre file
that
supports the new plugins. Your choices about what plugins from 3.1.0 or
3.0.0 to
load won't be affected, and will remain in-place in your old .pre files.

Of the above plugins:
init.pre (SA 3.0.0) loads:
	URIDNSBL
	SPF
v310.pre loads:
	Spamcop
	DCC (disabled by default)
	Pyzor
	Razor2
	AWL
	AutoLearnThreshold
	TextCat (disabled by default)
	WhiteListSubject
	MimeHeader
	ReplaceTags
	DomainKeys (disabled by default)
v312.pre loads:
	DKIM (disabled by default)

V320.pre only handles the new plugins for 3.2.0, most of which are
things that
used to be hard-coded into EvalTests.pm.

You really shouldn't have to do that for all of them. Only look at the
ones that
aren't loaded by default.

Makes sense, that's a v312.pre thing.
