Please read this document
for installation and release information about Lakewood Communication’s
XWALLFilter for Microsoft Exchange 2010. This document discusses the following
topics:
Overview
XWALLFilter is an add-on product for DataEnter's XWall (edge e-mail firewall and antispam solution). XWALLFilter enhances XWall's capabilities in sites which run Microsoft Exchange Server. XWALLFilter provides XWall with native, server based support for the Microsoft Exchange Antispam API and Junk E-Mail folder.
XWALLFilter examines all anonymous SMTP email entering your Exchange server from XWall. If one of the various XWall firewall filters (subject, text, html, spf, bayes, heuristic, image, etc) has been triggered and the XWall option "Mark subject and move to Junk E-Mail folder" has been selected, XWALLFilter routes the message to each mailboxes "Junk E-mail" folder automatically. This allows the network manager to configure one or all of the XWall filters as "Mark subject and move to Junk E-Mail folder" and let each user have final control over what is and what is not considered SPAM.
XWALLFilter pays attention to the Exchange per-mailbox SAFE SENDERS and SAFE RECIPIENTS list (Can be accessed in either the full Outlook client under Tools->Options->Junk Email or in Outlook Web Access under Options->Junk E-Mail). Any incoming email from addresses on the mailbox SAFE SENDERS list (or mailbox CONTACTS folder) is always placed in the INBOX and never placed in the user's JUNK E-MAIL folder. If the user finds good email in the JUNK E-MAIL folder, he or she can simply right click on the email in Outlook and select "Junk E-mail->Mark as NOT Junk" to have the address added to the mailbox SAFE SENDERS list and move the message back to Inbox in one simple operation.
XWALLFilter does not require users have the latest version of Outlook installed and may be used with any e-mail client since it runs upstream of clients on the Exchange server. If desired, users can simply use Outlook Web Access without any e-mail client installed on the desktop.
System
Requirements
The following
are the preliminary system requirements for XWALLFilter for Exchange 2010:
1. DataEnter XWall 3.46+ suggested (version 3.38 or higher is required)
2. 10MB (megabytes) of hard disk space
3. Both Local Administrator and Exchange Organization Administrator Rights
4. Exchange 2010 with Hub transport role installed
5. Microsoft Windows Server 2008 x64 (w/SP2) or Windows Server 2008 R2
6. In a multiple Exchange server environment, XWALLFilter should be licensed and installed on any Exchange Hub Transport Servers to which XWall is sending email (see XWall Admin utility Options->General->Exchange tab).
Installation Part-1 (Install XWALLFilter)
Note: This procedure should be completed on your server
running Microsoft Exchange. In sites with a single Exchange Server, XWall and
XWALLFilter may be run on the same server if desired.
1. Uninstall any previous version of XWALLFilter by
closing any open MMC consoles and running the product uninstaller from Control
Panel->Add/Remove programs (Windows 2003 Server) or Control Panel->Programs
and Features (Windows 2008+ Server).
2.
Run the XWALLFilter installer and
follow the on-screen instructions.
Note: No server re-start is required for installation; however some
Exchange configurations may require that the Exchange Information Store service
be re-started before XWALLFilter will function properly. If a service re-start
is needed, you will be notified by the installer and you can perform this
manually when appropriate for your site.
Installation Part-2 (License XWALLFilter)
Note: This procedure should be completed on the server running XWall. If you’re running XWall and XWALLFilter on the same server this is fully supported in single Exchange Server environments.
1.
Verify XWall is version 3.44 or
above by running the XWall administration utility (mbadmin.exe) and clicking
HELP->ABOUT. If you’re running an older version, please upgrade before
continuing by downloading XWALL.ZIP from DataEnter
(http://www.dataenter.co.at/download.htm), stopping the XWall service,
overwriting MBSERVER.EXE and MBADMIN.EXE in your C:\XWALL directory and
re-starting XWall.
2.
Enter the XWall Admin utility.
Select View-> XWALLFilter Exchange 2003/2007/2010 Junk E-Mail Folder Add-On
and select "Exchange 2003/2007/2010 with XWALLFilter installed". If
you’re running a 30-day trial of XWall, XWALLFilter is automatically licensed
in full function mode during XWall’s trial period and you may skip to
Installation Part-3. If you’re running a licensed copy of XWall and have not
yet purchased a license for XWALLFilter or desire a fully functional 30-day
trial, click the PURCHASE link.
3.
Enter the XWall Admin utility,
Select Help->Licenses->XWALLFilter. If you already have an XWALLFilter
license key (string beginning with ‘D’ and ending with ‘W’, example:
“Duj+0YBiANp/oOVrUWERBEhK0iEsiPsgJBUOsGgapKAHnHtPhuUAxNwfdW”), paste it into
the field LICENSE. If you have an XWALLFilter serial number (string with
dashes, example: “F0D2F21E-CCB0-11D0-A316-00AA00688B10”, click the ACTIVATE
link. The activation web site will issue you a license key to paste into the
field LICENSE.
Note 1: During activation, be sure to select “XWALLFilter for Exchange
2010” in the field PRODUCT.
Note 2: Your XWALLFilter Serial Number and License Key are valuable and
should be kept in a safe place for disaster recovery, maintenance renewals and
product upgrades. Public disclosure or use on more servers than purchased will
cause your license to be automatically disabled.
4.
Also in the XWall Admin utility
under Help->Licenses->XWALLFilter, verify that a VALID email address is
entered under the field “LICENSE E-MAIL” and then click OK. The e-mail address
entered must be valid e-mail address for the Exchange Server on which
XWALLFilter is running.
5. XWall should automatically restart in a minute or two and you should see an entry in the application event log on the Exchange server on which XWALLFilter is installed confirming your license has been enabled. A properly licensed installation will show an event = 15, “XWALLFilter has been enabled”.
Installation Part-3 (Configure XWall)
Note: This procedure should be completed on the server running XWall. If you’re running XWall and XWALLFilter on the same server this is fully supported in single Exchange Server environments.
1.
Enter the XWall Admin utility and
configure the filter action to "Mark subject and move to Junk E-Mail
folder" for those XWall filters (subject, text, html, spf, bayes,
heuristic, etc) you wish XWALLFilter to take action on.
2. If you don't want the subject line of filtered emails to be marked by XWall, simply set the subject marking strings to null in the XWall Admin utility under "View->Advanced Configuration->Mark Subject - 1/2".
1.
VERY IMPORTANT: Close any open MMC
consoles and server/performance monitoring applications.
2. Run the XWALLFilter uninstall from the XWALLFilter
program group or from Control Panel->Add/Remove programs (Windows 2003
Server) or Control Panel->Programs and Features (Windows 2008 Server or
Small Business Server 2008).
Note 1: No server re-start is required for uninstall; however the
uninstaller will perform the re-start of the Microsoft Exchange Transport
service automatically.
Note 2: If during uninstall you experience repeated prompts “XWALLFilter
is still loaded ...” and have closed all MMC consoles and monitoring
applications, please temporarily stop the "Windows Management
Instrumentation" service. If these steps fail to solve this problem, go to
http://www.XWALLFilter.com, click on SUPPORT and we will be glad to help.
How to Upgrade XWALLFilter
Follow the "Installation Part-1" instructions for this new release. You may skip the “Installation Part-2 and “Installation Part-3” if you have previously licensed XWALLFilter and configured XWall.
Troubleshooting
1. Examine
the application event log on the Exchange server on which XWALLFilter is
installed, filtering for entries with Source = XWALLFilter to confirm the
product has been installed and is running properly. A properly licensed
installation will show an event = 15, “XWALLFilter has been enabled” since the
last time the Microsoft Exchange
Transport service was started. If this event is not present, you may force a
refresh of the XWALLFilter license by re-starting XWall.
2. Verify
the mailbox specific Exchange 2010 "Filter Junk E-mail" option has
been enabled by logging into the mailbox using Outlook Web Access (OWA), then
select OPTIONS->Junk E-Mail, and verify the checkbox "Automatically
filter junk e-mail” is checked. Note that
this option is enabled automatically if this mailbox user is using Microsoft
Outlook 2003/2007/2010 in cached mode. If your users are not using Outlook
2003/2007/2010 in cached mode, or are using another email client (or an older
version of Outlook), you have two options: a) Enable this option manually in
OWA on each affected mailbox as described above or b) Run a script to enable
this option on some or all of your mailboxes at once. For option B, please
download the file "EnableJunkEmailFilter2010.zip" by following the
link in your product registration email. If you have not yet registered
XWALLFilter, please go to http://www.XWALLFilter.com/registration.
3. Verify
you have re-started the Exchange
Information Store if you were requested to do so by the XWALLFilter installer.
If your not sure, you can verify if this is needed by reviewing the XWALLFilter
installation log available in C:\Program Files\XWALLFilter\XWALLFilter.log.
4. Verify
that XWall is delivering email to the Exchange Server that XWALLFilter is
installed on.
5. Verify
that XWall is delivering the email to the Exchange Server that XWALLFilter is
installed on anonymously and not through an authenticated logon. XWALLFilter
assumes email delivered through an authenticated logon is trusted and is never
treated as SPAM.
6. Verify that a VALID email address is entered under the
field “LICENSE E-MAIL” in the XWall Admin utility under
Help->Licenses->XWALLFilter. The e-mail address entered must be valid
e-mail address for the Exchange Server on which XWALLFilter is running.
7. If the Exchange Edge Server Anti-Spam filters have
been installed (Check the Exchange Management Console under Organization
Configuration->Hub Transport->AntiSpam), make sure all filters except
“Content Filtering” are disabled by right-clicking on each and selecting
DISABLE. There is no reason to enable these filters since XWall is performing
filtering and having these filters enabled can interfere with communications
between XWall and the Exchange server. The Content Filtering agent may be left
enabled if you desire without risk of interference.
8. Verify
that the Exchange server on which XWALLFilter is installed has the Hub
Transport role installed.
9. Create
a brand new user and associated Exchange mailbox. Logon to the new mailbox
using Outlook Web Access (OWA), then select OPTIONS->Junk E-Mail, and enable
Junk email support by checking the checkbox "Automatically
filter junk e-mail”. Send email to this new
mailbox from an external email account which is not on your XWall whitelist
with a SUBJECT line that is listed in XWall under
Options->Blocking->Subject as being set to “Mark subject and Move to Junk
E-Mail folder”. Confirm that the email is routed to the Junk E-Mail folder
properly. If XWALLFilter works fine on this new mailbox but not on some existing
mailboxes, you may have rule corruption caused by a migration or import of
those mailboxes from PST files. Perform Microsoft knowledgebase article ID
924297 on an existing mailbox that is broken to confirm if you have this
Exchange problem. After performing this knowledgebase article, toggle the
"Automatically
filter junk e-mail” in Outlook Web Access
(OWA) OFF and then ON again before testing with an external email account.
