Hi Derek, You must be reading a different Exchange Kit :) 12. Configuring the Windows Server 2003-based ISA Server 2000 Firewall as a Filtering SMTP Relay [DOC] [ZIP] Spam is something we all have to worry about. ISA Server addresses the spam problem with its SMTP Message Screener. The SMTP Message Screener can filter SMTP mail using source address, source domain, keywords and attachment filtering. The SMTP Message Screener can be installed on the ISA firewall, an independent SMTP relay on the internal network, or on the Exchange Server itself. If you don't have the resources to put the SMTP filter on a dedicated SMTP relay on the internal network, then put it on the ISA firewall. This article gives you all the details on how to make it happen. 13. Configuring a Windows Server 2003-based ISA Server as a Secure Authenticating SMTP Relay [DOC] [ZIP] Remote users often connect to hotel networks that don't provide them with an SMTP server to send outbound mail. If your remote users use POP3 or IMAP4 to connect to the Exchange Server, then they need access to an SMTP server. You can create a secure, authenticating SMTP server on the ISA Server firewall itself that you users can connect to and send mail to anyone in the world. The ISA firewall can also act as an SMTP relay that accepts inbound SMTP messages for your domains and reject mail from spammers attempting to use it as an anonymous relay. This article provides all the details required to allow a secure authenticating SMTP relay and an anonymous inbound SMTP relay for mail destined to your own mail domains. 15. Installing and Configuring the Windows Server 2003-based ISA Server 2000 SMTP Filter and Message Screener on the ISA Server Firewall [DOC] [ZIP] Want to run the SMTP Message Screener on the ISA firewall and not waste resources on a second machine or risk putting it on the Exchange Server? Here's your fix. This article gives the details on how to make it happen. This article extends the information provided in the Configuring the Windows Server 2003-based ISA Server 2000 Firewall as a Filtering SMTP Relay article.

Nothing I read about the Exchange Kit suggests that it will assist in the setup of the SMTP filter/Message Screener. ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=isalist ISA Server Newsletter: http://www.isaserver.org/pages/newsletter.asp ISA Server FAQ: http://www.isaserver.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 Exchange Server Resource Site: http://www.msexchange.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this ISAserver.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
