Overwhelmed by Junk E-mail?
Is your mail server overflowing with spam and malware? Trash Finder can be your
solution. Trash Finder is a mail filter that operates as a plugin for your mail
server, providing filtering on dozens of criteria along with management of known
good mail. Junk e-mail has nowhere to hide with Trash Finder on the job!
What is Trash Finder?
Trash Finder is a plug in for a mail server. It is intended to be used on the gateway
mail server for small and medium sized networks, filtering all incoming mail into
a small business, school, or small ISP. It is not a filter for mail clients.
Currently, Trash Finder is available as a plug in for the IMS mail server (on Windows
NT, Windows 2000, Windows XP, or Windows 2003). We're
planning to make it available for other mail servers as well; so if you're
interested in using it with another mail server, please contact our
information department with details.
Trash Finder analyzes a message, decoding it into its parts. Each part can be
scanned for matching strings. This reduces "false positives" - messages which are
tagged as junk that are actually good. For instance, a URL filter is only checked
within URLs in the message; if the phrase occurs in some other part of the message,
the filter is not triggered.
Each filter can be set to treat the message as trash, spam, a virus, or discard
the message. Filtered messages (if not discarded) can then be examined to see if
they are good mail (which should be forwarded for normal processing), whether the
filters should be strengthened, or just to discard the message.
Choose the version that is right for you
Trash Finder comes in two editions: Trash Finder Pro and Trash Finder Classic.
Trash Finder Pro is the full-featured professional version of Trash Finder. It
includes junk mail analysis tools and more advanced filters. It is bundled with
an update subscription, so that it is continually updated to handle new trends
in spam and malware.
Trash Finder Classic is the original version of Trash Finder. It includes the
most useful filters, and is available as a free download.

The Trash Finder Manager
The interface to the Trash Finder filter plug in is the Trash Finder Manager. This
GUI program provides an easy-to-use interface to manage the Trash Finder filters.
Filters can be added, deleted, modified while the mail server is running.
The Manager also provides an extensive set of statistics on the incoming mail and
its disposition. This data can be used to fine-tune the filters, removing ones
that block too many good messages, and strengthening ones that are effective.
The Trash Finder Viewer (Trash Finder Pro only)
Trash Finder Pro includes a second GUI tool, the Trash Finder Viewer. The viewer
provides convenient sorting and analysis for messages filtered by Trash Finder.
The Viewer can be used remotely, not only forwarding and discarding filtered
messages, but also updating the Domain, IP, and Unknown Words filters from any
computer with network access and permission to the mail server.
The viewer provides one touch analysis of messages for domains used, suggesting
those that ought to be added to the Domain and IP filters. A few more clicks can
add the domains to the filters and dispose of the message. Here is part of the
analyzer dialog for a message:
The domain can be added to the filters simply by changing the action and clicking
on "Delete Message" (not shown). The Viewer does all of the work.

As the oldest independent Ada compiler
publisher in the world, we possess a unique
perspective. All of our products are
compiled and written in Ada using
Janus/Ada. In 1981 we developed the very
first Ada compiler for the PC, and have
since been the first to introduce Ada for
Windows and Ada 95 for Windows NT. More recently, we developed Claw, the only
compiler-independent Windows interface for Ada 95, along with a GUI builder.
We're clearly the leader in Ada for the personal computer.
