[2] Compatibility with Exchange 2013 Service Pack 1 requires installing a bugfix from Microsoft. Learn more about this.
The recommended system configuration is that of Microsoft® Exchange. In overall, introducing ORF to a system that is already capable of running Exchange or IIS SMTP smoothly does not add significant further load to the system. However, estimating the load generated by ORF is very difficult, because it depends much on the features and configuration used.
ORF requires considerable disk space for logs, about 500 bytes per log entry on average. This results in the following average disk space requirements:
| Email Traffic | Logs for 1 day | Logs for 30 days |
|---|---|---|
| 1,000 / day | 488 kB | 14 Mb |
| 10,000 / day | 4.5 Mb | 143 Mb |
| 50,000 / day | 24 Mb | 715 Mb |
| 100,000 / day | 48 Mb | 1.4 Gb |
| 500,000 / day | 238 Mb | 7 Gb |
Log retention can be configured in ORF (defaults to 30 days).
