Free BSD 7 - Not able to receive messages

[Blessan]

I have installed free bsd 7 on on Intel Xeon Machine with 1 Gb ram.
But i cant use the mailing facility .. i can send mail by typing [mail
username]  then follows the subject and message then EOF. but i when i check
mail of that particular user it shows No mail for that user ??
Why is it so .. ? Do i have to reinstall ..
Also i have to configure my network card each time i reboot..
Plz reply
