My main IMail server is very secure and I have no problems with it. I use the SMTP feature of IIS6 on a different server as my "store and forward" mail server in the event my IMail box is down. This is where the problem is!
All the spammers run their dictionary attacks on my secondary "store and forward" server. This server accepts all mail as long as it's to a valid domain. So this means that the server will accept ALL of those messages from a dictionary attack as if it were running a nobody alias. It's not an open relay. The store and forward server then tries to deliver those messages to my main IMail box, and this is where IMail weeds out all the invalid messages. My store and forward server is getting hit with about 500 messages a minute. Only about 2% of those messages are valid. The bandwidth this uses really pisses me off. Are the spammers intentionally looking for lower priority MX records? Is there any way to eliminate this problem (maybe I've overlooked something in the setup)? Any suggestions would be appreciated... I'm sure others have this same problem!
