can share some backend (MTA) statistics. I need to build a test server to store
emails and give imap/pop3 (this is already working), but i need some
&quot;real-world&quot; info about email flow to big email servers.<br>
<br>
I have this kind of questions for deployments of servers with more than 1000
users:<br>
<br>
- How many emails are recieved per day or per hour (bussiest hours)?<br>
- Average Quota?<br>
<br>
żAny other relevant data?<br>
<br>
This is just to get an idea any comment will be appreciated.<br>

Thanks!</span></font></p>
