for installation and release information about Lakewood Communication’s
XWALLFilter for Microsoft Exchange 2003. 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 2003 Server and/or Small Business Server 2003. XWALLFilter provides XWall with native, server based support for the Microsoft Exchange 2003 Antispam API and Junk E-Mail folder.
XWALLFilter examines all anonymous SMTP email entering your Exchange 2003 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 2003 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). 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 minimum system requirements to install and run XWALLFilter for Exchange
2003:
1. DataEnter XWall 3.47+ suggested (version 3.38 or higher is required)
2. 10MB (megabytes) of hard disk space
3. Domain Admin rights to install and configure
4. Microsoft Windows 2000 SP3+, Windows 2003, Windows 2003 R2, Small Business Server 2003 or SBS 2003 R2
5. Microsoft Exchange 2003 (with or without SP1 or SP2)
6. In a multiple Exchange server
environment, XWALLFilter should be licensed and installed on all Exchange 2003
Servers which XWall is sending email to (see XWall Admin utility
Options->General->Exchange tab). In an Exchange FE/BE
(Front-End/Back-End) environment, XWALLFilter should usually be licensed and
installed on all FE servers.
Installation
Part-1 (Install XWALLFilter)
Note: This procedure should be completed on your server
running Microsoft Exchange. In sites with a SINGLE Exchange Server or Small
Business Server, XWall and XWALLFilter may be run on the same server if
desired.
1. Run the XWALLFilter
installer and follow the on-screen instructions.
Note: Previous versions of XWALLFilter are automatically upgraded. 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 Standard or SBS Edition)
Note: Follow the licensing instructions in this section for XWALLFilter Standard and SBS Edition only. For XWALLFilter ISP Edition please ignore this section and follow the instructions for license installation sent with your ISP edition license file and skip to Installation Part-3 below.
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 3.47 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
2003” 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.
Note 1: No server re-start is required for uninstall; however uninstall requires
that the IIS Admin Service be re-started. On Windows 2000 servers, the
uninstaller will prompt for you to perform the re-start of the IIS Admin
Service at the appropriate time during uninstall. On Windows 2003 or above
servers, the uninstaller will perform the re-start of the IIS Admin 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 SMTP 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 2003 "Filter Junk E-mail" option has
been enabled by logging into the mailbox using Outlook Web Access 2003 (OWA),
then select OPTIONS, and verify the checkbox "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 "EnableJunkEmailFilter.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. Make
sure that the Exchange SMTP Virtual Server filter options Sender, Recipient,
Connection and Sender ID are unchecked on the Exchange 2003 server that
XWALLFilter is installed on. The filter options can be found in Exchange System
Manager under SERVER->Protocols->SMTP->Default SMTP Virtual
Server->General Tab->Advanced->Edit (where SERVER is the name of the
Exchange 2003 server). There is no reason to enable these SMTP virtual filters
since XWall is performing this filtering.
5. Verify
that XWall is delivering email to the Exchange 2003 Server that XWALLFilter is
installed on.
6. Verify
that XWall is delivering email to the Exchange 2003 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.
7.
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.
8. Create a brand new user and associated Exchange
mailbox. Logon to the new mailbox using Outlook Web Access 2003 (OWA), then
select OPTIONS, and enable Junk email support by checking the checkbox "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 "Filter Junk E-mail" in
Outlook Web Access 2003 (OWA) OFF and then ON again before testing with an
external email account.
