Hi , friends , Here is my problem :
I was recently contracted to design a accounter of Mail :
There is a LAN having serveral computers( PC ) with IP address ( perhaps
fault IP address with proxy server) , in these computers only 2 or 3 can
send mail freely while the others can not , the LAN links to the Internet
with a router , Now I want to know :
1. Wether I can limit the user in the LAN only to use my mail server
2. Wether I can count how many mail message sent from EACH computer , how
large each message is ?
3. Wether I can set up a mail server that can open mail channel optionly
to a special computer or close it
4. Wether I can know how long each computer on the Internet
well , I don't know if my question is comform to the subject of this mailist ,
I think perhaps they are related to security items , or very sorry about my
rash !
Thanks !
