SMTP relay vs. SMTP server

SMTP relay and SMTP server are two terms used to describe different ways of sending email messages over the internet or within a network. An SMTP server is a computer program that acts as a mail server, receiving incoming messages and forwarding them to their intended destination. It is responsible for sending outbound emails from the user's email client, such as Gmail or Outlook. On the other hand, an SMTP relay is a service that is used to send email messages to the server for further processing and delivery to the recipients. It is typically used for bulk email delivery or for sending newsletters. SMTP relay is more suitable for large organizations that send out high volumes of emails, while SMTP server is more suitable for individual users and small businesses.
