Hello, I had to rebuild this system from scratch last week. I reconfigured services once I got it going and dns is working, email is partially working and some domains are getting rejected others are not all the rejections have to do with relay access. I don't know which configuration to check. mail_relay_recipient is empty,, mail_transport is empty, mail_domain has content, mail_user has content, mail_forwarding has content, Something is slightly wrong and I'm not sure where to look. Please let me know what you need from me.
