Sure. Let the drooling begin. :-)
* Added To address pass/no delete filters. This allows messages with
specific
recipients to be protected/passed.
* Added Subject pass/no delete filters. This allows messages with specific
subject text to be protected/passed.
* Added Domain/IP filter. The domain/IP filter provides a disk-based (not in
the registry!) method of recording domains and IPs.
-- More information and options (separate actions for different uses;
more detailed statistics);
-- Can be updated remotely;
-- Exact matching (other than that subdomains match) for fewer errors;
-- The domain extractor understands common redirectors, and extracts the
*real*
spammer domain;
-- Domain Web and Mail IPs recorded;
-- IPs (and IP ranges) can be filtered; if a URL resolves to a known IP,
it
can be filtered (without dealing with the domain separately);
-- Automatic downgrade for "stale" domains and IPs; if the domain or IP
has not
been used for a long time, it changes the actions to Trash. (That
protects
against a legit. user taking over a spam domain and having their mail
blocked
for no reason.) (This feature can be turned off for particular domains
by
setting the domain to "permanent" - that's useful for obvious porn and
the like
domains.)
* Added unknown words filter. The text of a message is checked against a
dictionary;
if there is too high a percentage of unknown words, the message is
filtered. Like the
domain filter, the known work list dictionary can be updated remotely.
* Added Viewer application:
-- Replaces Spameye; shows the decoded message that TF sees for filtering;
-- Shows the reason that TF filtered the message;
-- Shows all three (Trash, Spam, Virus) of the TF filter directories;
-- Contains a spam domain analyzer; shows the most used four domains in
the message,
and lets you add/update them in the Domain/IP filter;
-- Automatically deletes messages that don't need further analysis;
-- Checks relayed messages for unknown words, and lets you add them
(selectively)
to the dictionary of known words.
I've still got parts of the IP editor to finish, plus a number of the UI
improvements suggested for the viewer (from the December alpha test), and
the documentation (none on the Domain/IP filter or unknown words filter
yet).
For the record, the IP filter is catching (and deleting) about 8% of my
incoming mail, and the unknown words filter is deleting (over 80% unknown
words) about 7% of my incoming mail. (I've turned off the character set
filters, which accounts for about 5% of the unknown word mail.) A lot of the
mail that the IP filter catches is uses of new domains that point at the
same old spammer servers.
