You have two options really. <br />
<br />
1. Move to Exchange 2003 on Windows 2003. Having a eight year old OS in production is not really something that is any good long term. <br />
<br />
2. Use a third party tool to provide the recipient filtering and tar pit. Vamsoft ORF will do that for you. <br />

<div class="content wysiwyg-content">
It appears there are tons of emails trying to be sent out from our system. I opened up these emails and some have a from address of postmaster@ourdomain.com and other from field is black. <br />
<br />
This appears to be a NDR attack. Now I know somewhat about the filtering options but we have windows 2000 and it was not suggested to apply any filtering because of AD harvest issues. <br />
<br />
Since we do not have windows 2003 to turn on tar pitting option what can I do? This is causing all kinds of bouncebacks to employees trying to say they sent an email to ex-employees that no longer exist.<br />
<br />
Our queues are really starting to fill up quickly after I cleared them.<br />
