Ok. But when it is up to OS? when the option is enabled or disabled? I've just upgraded to current RC and got quite a load (about 9-10) caused by vdelivermai and vmstat suggests that I got IO bottleneck now. Besides I see lots of vdelivermail running and every mail spends now lots of time in a queue, even when it is local. Any ideas, please? Solt PS> Ken, sorry about two copies of this mail. BTW: Could you set default Reply-To: to list address? It would be easier when replying.
