Hi,<br />
<br />
Our exchange server(s) is being used to spam. &nbsp;It is open in two ways:<br />
<br />
<br />
<br />
It is relaying any email from within our network to the outside from any domain and user <br />
It is relaying OUTSIDE our network from people forging usernames without password. <br />
&nbsp;<br />
How do I fix? Help!<br />
<br />
Thanks.
