For the moment i have disabled sendmail (because i utilize only web email).

$ fstat | grep internet | grep -v -e '>' -e '<'

_dhcp    dhclient   28736    8* internet raw ip 0xd6199000

I would like do some other optimization.

Also i have another question.
How can disable service without restart the OS?

Note:
I have read the Faq 10.
