a client of us has an issue with the Exim server, when somebody mails to [email protected] exim accepts this. The problem on this is that many spammers approach them like this.
They want to block all mail which has not been sent to @domain.com.
Is it possible to reject all mail which has not been sent to @domain.com but @subdomain.domain.com ?
Thanks in advance.
