Is the host sending internally through your Exchange server or are you seeing lots of messages in the outbound queue from &lt;&gt;&nbsp;waiting to go out?<br />

What Anti-Spam software do you have installed and is it performing AD lookups to filter invalid recipients?<br />

Does your mail server receive emails directly from the web or via a 3rd party which spam-filters them first?<br />

Is the host sending internally through your Exchange server or are you seeing lots of messages in the outbound queue from <> waiting to go out?

What Anti-Spam software do you have installed and is it performing AD lookups to filter invalid recipients?

Does your mail server receive emails directly from the web or via a 3rd party which spam-filters them first?

Yes internally through the exchange server. there doesn't seem to be a lot but enough to cause concern.<br />
<br />
We are using Mcafee SAAS for spam and virus scanning and they are 3rd party relay host. <br />
<br />
When I use the massage tracking tool on the exchange server all I see is the host of the exchange server and Mcafee servers ip addresses. What &nbsp;I need is the Mac or IP address of the host sending to exchange2007.

Is there a way to find the IP address of the host sending messages from Exchange message tracker or some other way. I'm trying to track down a host that is sending a lot of messages.<br />
<br />
I've check THE RELAING and that is limited to servers.

Exchange 2007 sending spam

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

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.
