The reason why I need to use putty because I want to configure my Linux in my workstation then stop the spams. I recieve everyday around 15 to 20 spam emails.
Please help me again step by step because I dont have any idea on this matter. Thank you very much
These are the platforms:
Client: Windows XP SP2, Putty v0.58
Server: Red Hat 8.0 sendmail, mail was already setup by other people.
They created the user by this way "adduser -g users /bin/false username"
I know that "/bin/false" was set to not allowing the user to connect remotely. I dont know on how to check if the user was /bin/false or /bin/true.
This is the sample full header of the spam email.
mail.sgp.com.ph is my previous domain.
modu.com.ph is my present domain.
