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.
Additional Info:
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.

Status:

Place a filter on the sendmail program disallowing

every@

in the

To:

field of all incoming email. Have an autoreply message that bounces the spam back where it came from.

Or set up spamassassin or similar on the mail server

Is every your username? if not, make sure sendmail reject mail to unknown users

every@modu.com.ph is the email account for everyone. So therefore, I need to recieve the incoming email containing every@ in To: field.

The spam sends also in our individual account (e.g. eros.sy@modu.com.ph).

I would like to use spamassassin but I was afraid to install because I do not have any support. Please teach me to setup spamassassin step by step because I am almost a month of using Linux (Red Hat 8.0 sendmail).
