Exim send emails using server hostname instead of clients domain name? Even spf looks to be not set, even if I have set it for the specific domain, but not for server (main domain), which is showing for some reason in headers. Headers look like: I would like Received: from client.domain (static.148.72.xx.xxx.clients.your-server.xx [148.72.xx.xxx]) Also, I have no idea why is showing from nobody by server.domain.com instead of . Any suggestions and solutions are more than welcome.
