R: R: R: R: Mailscanner slow queue

[Marcello Anderlini]

I've noticed that this time could vary many.
I've done some test now and the answer range could be from 1 mesc to 406
msec

My internet line does not appears to be saturated.
In my named.conf I have set to forward request to my ISP dns.
My sistem  it's a xeon dual core and cpus runs between 85% and 92%

This it's my memory usage
Mem:   2055628k total,  2006176k used,    49452k free,    53708k buffers
Swap:  2031608k total,    18532k used,  2013076k free,   413196k cached


Thanks again for your help

is your internet line saturated ? do you have a upstream ISP where you could
forward your DNS requests ? what is the load on your system ? how much free
mem does it have ?
