Have a self hosted Exchange server and Monday started to get reject messages :
e.com rejected your message to the following e-mail addresses:
e.com gave this error:
xx.242.94.188 Rejected - see http://www.spamhaus.org
Same for .82 and .83
I changed the static IP to a new one yesterday and now some sites work others do not.
so I changed to a 3rd different static IP and within 5 or 10 minutes Outlook Exchange mail users were getting bounce backs courtesy of Spamhaus again.
Only two blacklists report them ,any ideas?
