Hello all, need a help. We use postfix for mailing. Our domain are hosted on our server. We created a new vhost on our server for our client and started to deploy all files, but DNS changes wasn't changed. Now we have a problem with local email delivery, because then I try to send email to client, i get error. In case our host and our new client host are on same location, so looks like server firstly reach local MX of our server and gets error "Mailbox not found".
How to fix this issue and let server search real MX records?
