DNS and MX - Email Architecture

The web mail connects to the local MTA, which is operated by the ISP. SMTP is used in this connection through port number 25. In case of heavy load, an email queue id formed, while the MTA processes each email. Rarely does the email go directly to the receiver’s inbox when it has entered the cloud ( i.e. Internet) . Instead, it is accordingly routed, depending upon the availability or non –availability of MTA’S. MTA’S before it’s delivered.

The IP addresses are the only thing that computes understand; the MTA typically looks at the domain name (the part after @ sign) in the DNS to find the mail exchange (MX) record for that domain. Before this, domain name resolution has to be done. Starting with top-level domains like .org, .edu, .net (like this these are 13 different domains)

Another important of the email architecture is that push mail which is found on mobile phones, PDA’s and smart phones. In this type, the internet connection is always “on” and the email is immediately delivered to the device, the instant it arrives on the server. In many cases only the header may be retrieved to the handheld so that bandwidth is not wasted. IMAP4 supports push mail, while blackberry uses its proprietary push mail in its devices.
