It's a standalone Debian box running exim in what I believe is
a pretty default configuration. I just use the ordinary
pon/poff scripts to connect to my ISP and I use their
nameservers. I don't see anything else using my bandwidth.

Isn't there some parameter I could use to disable the DNS
lookups? (if it makes any sense to do so)


Thanks,

Morten
