mqueue.in build up

[Stephen Lane]

Hi Mike,

Running 7 MailScanner children ( FYI - have played with this some seems to
work better when above 5 )
Processor(s) :  2
Model :  Pentium III (Coppermine)
Chip MHz :  866.274 Mhz
Cache :  256 KB
System BogoMips :  3460.3

No local caching nameserver on mail server does lookups to secondary dns
first then primary second this is becuase we set secondary to retrieve
MAPS-RBL+ updates

Resolution order is Hosts, DNS, NIS, NIS+
Search Domains - None

Thanks
Steve
