Are that the two servers multiplexing your traffic between inside and
out? 46,000 messages/day are around 30 messages/minute total average and
probably 60-90 messages/minute peak, and that's two machines in total? I
see. I run as low as 400 messages/minute, peak being 1500/minute - on a
single node. I know I can reach 2000-2200, if needed. The systems for
internal delivery run at 100-200 messages/minute when operating regularly.

I sure wouldn't mind a few hundred systems more to make my life simple. ;-)
But as I said: Only small sites can afford that.
