What is an MTA vendor?

An MTA vendor provides the server software responsible for transporting email between systems using SMTP. Classic engines include Sendmail (the original, created in 1983), Postfix, Exim, and PowerMTA. These engines handle queueing, retries, throttling, and routing. They are the powerful engines inside every mail ship, pushing messages from one harbor to another.
