Hello,<br />
I am running MS Exchange 2003 behind a firewall. Yesterday I went into ESM Server/Queues I found that there is a large volume of spam email coming from administrator@&quot;mydomain&quot;.c<wbr />om being sent to domains all over the globe. I froze as many as I could but new ones keep popping up. <br />
I have checked and found that my server is not a relay server. <br />
I've tried to run RootkitRevealer in a console window but I keep getting the error message that it must be run from a console window..... <br />
I am new to Exchange and am looking for some guidance as to my next step and or some reference material.<br />
<br />
Thank you in advance for your help.

Exchange 2003 Sending Spam

Interactions between email servers and clients are governed by email protocols. The three most common email protocols are POP, IMAP and MAPI. Most email software operates under one of these (and many products support more than one).  The correct protocol must be selected, and correctly configured, if you want your email account to work.

Email Protocols

Software is any set of instructions that directs a computer to perform specific tasks or operations. Computer software consists of programs, libraries and related non-executable data (such as documentation). Computer software is non-tangible, contrasted with computer hardware, which is the physical component of computers. Software written in a machine language is known as "machine code". However, in practice, software is usually written in high-level programming languages than machine language. High-level languages are translated into machine language using a compiler or interpreter or a combination of the two.

Software

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.
