Hello<br />
<br />
We have an Exchange 2003 SP2 server with Intelligent Message Filtering turned on. &nbsp;We are seeing a lot of spam messages get past the IMF and make it into user's inboxes. &nbsp;<br />
<br />
I noticed than on all of the messages that get through, their is no SCL rating in the header. &nbsp;Any message that has a SCL rating is properly recognized as spam.<br />
<br />
Why would some messages not have that, is it a configuration problem with Exchange, IMF, etc....<br />
<br />
Thanks

SCL Missing in Exchange Email

Exchange is the server side of a collaborative application product that is part of the Microsoft Server infrastructure. Exchange's major features include email, calendaring, contacts and tasks, support for mobile and web-based access to information, and support for data storage.

Exchange

Within Internet message handling services (MHS), a message transfer agent or mail transfer agent (MTA) or mail relay is software that transfers electronic mail messages from one computer to another using a client–server application architecture. A MTA implements both the client (sending) and server (receiving) portions of the Simple Mail Transfer Protocol (SMTP). The terms mail server, mail exchanger, and MX host may also refer to a computer performing the MTA function. The Domain Name System (DNS) associates a mail server to a domain with mail exchanger (MX) resource records containing the domain name of a host providing MTA services.

Email Servers

Microsoft Outlook is a personal information manager from Microsoft, available as a part of the Microsoft Office suite. Although often used mainly as an email application, it also includes a calendar, task manager, contact manager, note-taker, journal, and web browser.
