SMTP (Simple Mail Transfer Protocol) is a server-to-server protocol that assists in email transmission through Transmission Control Protocol/Internet Protocol. Here, you can either use DataTrust SMTP or custom SMTP. To establish custom SMTP, you need to add the parameters such as Email Address, SSL, and Port. Simultaneously, you can also specify if authentication is required or not.
