Minor feature requests (hopefully in V5):
- yearly graphs (had them in V4), in addition to daily/weekly/monthly;
- graphs to show also maximum/peak values, not only averages (which "smear out / low-pass filter" the truth over time);
Major feature requests (for V6):
- SIP proxy;
- multi role administration, notably roles with lower priviledges, such as for example allowing the inspection of the quarantine of the SMTP proxy, and to forward "false positives" caught by the Spam filter;
