SpamSieve has been updated to version 2.7.

SpamSieve gives you back your inbox by bringing powerful Bayesian spam
filtering to popular e-mail clients. It learns what your spam looks
like, so it can block nearly all of it. It looks at your address book
and learns what your good messages look like, so it won’t confuse them
with spam. Other spam filters get worse over time as spammers adapt to
their rules; SpamSieve actually gets better over time as you train it
with more messages. SpamSieve doesn’t delete any messages–it only
marks them in your e-mail client–so you’ll never lose any mail.
SpamSieve works with any number of mail accounts, of whatever types
are supported by your e-mail software (e.g. POP, IMAP, Hotmail, AOL).
When using IMAP, SpamSieve on your Mac can even keep the spam off your
iPhone.

This update includes the following enhancements:

* Now requires Mac OS X 10.4 or later.

* Made a variety of accuracy improvements, focused on dealing
with obfuscations, image attachments, URLs, and HTML.

* Improved corpus speed and memory use.

* Made various improvements to the column widths and alignments
in the rules and corpus windows, and added alternating row
colors.

* Fixed a rare problem where Apple Mail on Mac OS X 10.5 might
hang if you trained a message as spam while Mail was
downloading messages.

* If the OS reports an error when playing a sound as an alert
sound, SpamSieve now plays it using the normal sound channel.

* Increased the range of possible values for the uncertain spam
threshold.

* Improved sorting of sound names in the pop-up menu.

* Fixed bug where SpamSieve wouldn’t launch if the “Microsoft
User Data” folder had been replaced by an alias file that was
invalid.

* No longer shows the **Reset Corpus/History** alert at launch
if you hold down other modifier keys in addition to
Command-Option.

* Updated the Dutch localization.
