Prevent spam which appears to be sent from your own domain

Last months you may receive spam which looks like to be sent from an account from your own domain. When you investigate the issue you will discover that this it not the case.

Microsoft Exchange couldn’t start transport agents. The Microsoft Exchange Transport service will be stopped. This is one of the errors you may get when you’ve got a corrupted transport agent. This can cause that the transport service won’t start anymore as you can see in the example, which causes that the mail traffic will stall.
