Hello all. After an entire morning of trying to track down the cause of this problem, I turn to you. Specs are as follows:
Windows Server 2003
Lotus Domino E-mail Server
Symantec Antivirus Corporate
Upon receiving reports from various users about mail delivery/receipt delays and large amounts of SPAM messages this morning, I began to examine my Domino server's routing logs for any problems. I found that it has been sending out very large amounts of spam messages all morning. From the logs it appears to send messages to various domains (some familiar, some not) and then it attempts to route return messages back to arbitrary accounts in my domain. (none of which have been valid so far).
Now, I have completed scans with Symantec Antivirus on the actual machine that Domino server is running and on nearly all client machines and other servers on my domain. I have found a few viruses here and there but NOTHING HAS STOPPED THE SPAM! I can't identify any "rogue" processes running on any of the machines either. Everything looks normal but all of this is going on behind the scenes.
Can anyone please help? I would give 1000+ points if I could. I am willing to check anything. Lotus Domino/Notes checks are welcomed too.
Thanks so much in advance.
