What is the function of a Mail Transfer Agent (MTA)?

An MTA is a programme that sends and receives electronic mail from one network node to another. It performs its function using the SMTP (Simple Mail Transfer Protocol) protocol.

There is an email client on a network node that is used to send and receive messages to and from the mail server; an email client uses the SMTP protocol as well, but it is not necessarily an MTA.

On a mail server, MTAs are installed, and email programmes such as Mozilla Thunderbird, Evolution, Microsoft Outlook, and Apple Mail are installed on a mail client (user computer). Also check Investment Apps For Android
