hi

I have an admin email and its not posted in website or anywhere . No one knows existance of this email. it was all working before but now all i see is spam. How do people get hold of my email and send 1000s of spam email to our server?

How do i resolve this? Moving to spam folder is ok. But any otherway to block people hitting our email servers?

thanks
