Go on, have a guess
mailnull is the user under which exim runs. You're looking in the wrong place if you're trying to identify a spammer on the server.

Hello

I want disable server to not send mailnull if a spammer send email to my server and address no exists.

Example: spammer send email to [email protected] but this email dont exists and server send to spammer a message of error. I want disable this. I want make server dont send email of erro to spammer.

Thank you
Konrath

That's an extremely bad idea.

You should send back a RCPT failure by using :fail: on the Default Address for a domain.

The alternative that you're looking for is to set the Default Address to :blackhole: but that is a bad idea for several reasons. The main one in this case is that you're encouraging the spammer to keep sending emails to those addresses because you're effectively telling them that the email has been received and accepted for delivery. The other reasons are explained here:

I know your site and have dicionary attack instaled in my server. Great script.

Yes, blackhole no is recommended.

Thank you
