Emails routing and DNS chain



Which DNS you check: When e-mails does not arrive to it's intended mailbox. Assuming that sender and receiver are operating normally. Sender is an ISP so their routing is counted-for up-to next BGP or Exchange point. Destination is major e-mail provider with its own domains.


or may someone elaborate on current email routing practice used to rout mail between mail-servers located at different autonomous systems.
