I'd recommend 10 connections per concurrent account that connects to |
| 42 |
the server from the same IP. If you're running multiple accounts, like |
| 43 |
kashani-list@ and kashani@ in my case, you'll want at least 20. Same |
| 44 |
thing applies if you're running webmail for multiple account because all |
| 45 |
account access will originate from localhost. |
