Mail server problem
Hey guys,
I have set up a mail server, using courier IMAP and postfix. The thing is recently users receive spam emails from "support@domain.com" telling them their password is updated and they have to click on the link to confirm and for any other issues contact "support@domain.com".
Question is when I look at the headers of the emails there is no "Received:" part so that I get the IP address of the MTA sending the email and block it.
Thanks in advance.
