I am trying to create a destination NAT SMTP intercept server. I need this because for SPAM reporting our upstream are providing our NAT gateway IPs instead of our client's internal network IPs and now they are blocking us.<div>

We run Cyrus with Murder at Oregon State University for over 30,000 users.<br>
I don't know if there is any practical limit on the number of mailboxes<br>
Cyrus Murder can support, but it must be a lot larger than 30,000 or<br>
70,000. We support these users with only 3 backends and 3 frontends.<br>
It's all a matter of giving your Cyrus servers enough I/O.<br>
