Well your wrong with IIS SMTP, with the right script and editing you can run any win mail server plus + iis smtp as long as you use two ip's one for mailenable, then one for shared IIS, anyways thats off topic.
Well its my first look at mail enable but in general all mail servers do the same.
If you read the manual under smtp it recomends you to
"For a server on the Internet, the best relay setting to have is to only have Allow relay for authenticated senders checked, and leave Allow relay for local sender addresses unchecked. This will make everyone who wants to send email out via the server provide a username and password."
Next in the smtp security section
"Authenticated senders must use valid sender address
If this is selected, users with authentication to send email must configure their email client with a valid email address that is assigned to the mailbox they are using to send on. This option is used to force clients to use a legitimate email address, thereby reducing the possibility of spam."
Next
"Restrict the number of recipients per email" try setting to 20
Next
"Drop a connection when the failed number of commands or recipients reaches" set to 5
Next
SMTP Logging - Activity Log make sure this is enabled
I've never used mail enable before but all that info is in the mail enable 2 manual, if you want drop me an email and i will see if i can help you out finding the source of the spam.
You might also want to look at the mailenable forum for more detailed help.
We have used merak for the past 2 years, we have only had one spammer in all that time, we locked down more smtp settings so in the event someone sends spam and it fails to be delivered it bounces back to the sender and also a copy to us. We limit number of connections, messages which can be sent.
