ECARD VARIANT
welcome letter.
The first variant of the Ecard Zombie
showed up in my Inbox today. It thanks you for signing
up and includes a link to a website .... bad news of
course. But there is good news. Your current Xwall (3.29+)
can block the ip address. Add a string http://#.#.#.#
in admin-> option-> blocking-> html
ECARD greeting
card spam is presenting new issues.
Some Ecard messages are downloading zombie
viruses by just opening the message. What makes it worse
currently the virus is undetectable by most virus scanner.
We recommend that you add subject blocks in XWall for
words like ecard, postcard, greetingcard, school-mate,
familymember, class-mate and so on. Many of these fake
ecard messages are caught already by the CCS, SLS and
SURBL filters.
PDF
the latest spam vehicle
It seems the spamers figured out that
you consider PDF as save to pass through your spam filter.
You can't just block PDF's or you loose invoices, documents
and other things typically emailed as PDF. The PDF issue
is addresses in the current XWall beta releases and
you find additional help in the forum under Image
Spam.

Compatibility
 The
XWall spam filter is compatible with all professional
versions of Windows and Windows servers including the
Microsoft Small Business edition servers series 32bit
or 64 bit. XWall may also be used with Notes, Groupwise
and other non-Windows environments. This however requires
that XWall is installed on a separate machine running
Windows.
XWall supports all versions of Microsoft
Exchange Server including 5.0, 5.5, 2000 and 2003. XWall
can be installed on the same machine as Exchange or
on a separate system. The system can be inside or outside
your network. Often XWall is used as a SMTP firewall
in the DMZ. XWall supports SMTP mail servers including
Lotus Notes, Novell Groupwise, Imail and many others.
Application
The XWall email spam filter is found
in situations ranging from a handful of users to large
scale cluster servers handling 15,000+ mail accounts.
A single XWall server often filters the mail for an
entire school district or university. The licensing
is per server based. One Exchange server requires one
XWall license.
A special XWall ISP is available to ISPs
and ISP-like operations. It allows filtering all email
for the ISP and forwarding it to multiple servers located
at the ISP.
Installation
The XWall setup is painless and does not
install any plug-ins nor does it hook to your Exchange
server. Xwall can be put in the mail stream or removed
from it with a simple port switch. The install wizard
automatically configures XWall for your system asking
only a minimal number of questions.
XWall is server based, installs in front
of your Exchange server and does not require any software
on the client system. XWall may function as application
or as service on any NT class system.
Benefits
While other spam filters may also filter
the mail in front of exchange they send it right to
it after filtering it. You still end up with all the
headaches and capacity issues. XWall with the ESAT option
keeps all the spam outside your Exchange or SMTP mail
server. Yet the users are informed about any blocked
email and can retrieve it. This feature is available
for all mail systems and not limited to some versions
of Exchange. The spam gets automatically deleted after
a preset (by you) time.
Components
Xwall features a long list of filter and
mail handling components. It's not just all about spam.
Xwall offers features like outgoing e-mail disclaimers,
outgoing e-mail encryption and signing. Read
