[linux-help] Re: SMTP help

Hello David,
We do our SMTP blocking at the core switch level with Access Control lists
(we use cisco).  I;m not sure how you'd go about filtering SMTP at the OS
level that affects the entire network. Then again it's 8 am and I have'nt
had a donut yet so i'm not firing on all cylinders.

Hi, I'm a new in linux world

I do't know much about SMTP however my job required me to do somthing with
it.

I was required to modify so smtp only able to listen conndtion base of the
IP number.
in other word if the address is from n.n.n.0 to n.n.n.255 then alow this
connection to the smtp.

just a clue what we want is set up so postini (email spam filter) able to
send email but not other.

any help will be great
thanks
