MX Resovler Component Demo MxDemo32.zip(124 Kb)

A few words about MX records

Let's consider the following situation: SMTP server (or your application) needs to send email to jdoe@domain.com. The logical solution is to connect to another SMTP server at domain.com and relay the message to it, but the existence of domain.com does not automatically mean that that particular domain is running SMTP server. Even more, most likely it is not. That's why you need to query the DNS server about the servers which have the information about the domain you want to relay the mail to. The addresses of these servers are called Mail Exchanger, or MX records. TmsMXResolver components queries DNS server and retrieves MX records for you.

If you are planning to create SMTP server, or email software which bypasses the fixed SMTP server and relays the messages by itself, you need TmsMXResolver component.

You can find more information about MX records from:

• rfc 974 - Mail Routing and the Domain System

• rfc 1034 - Domain Names - Concepts and Facilities

• rfc 1035 - Domain Names - Implementation and Specification

Currently MX resolver component is available only for registered users of the Internet Mail Suite, since it uses the core units from IMS. In other words, you can register MX Resolver only if you are the registered user of IMS.
