Types of SMTP relay?

SMTP relay refers to the process of forwarding emails from one server to another. There are two main types of SMTP relay: internal and external. Internal SMTP relay involves forwarding emails within a local network, such as within a company's email system. External SMTP relay involves forwarding emails to another domain or email provider. Internal SMTP relay is generally more secure and reliable, as it can be controlled and monitored within the organization's network. External SMTP relay is often used for larger email campaigns or for sending emails to recipients outside of the organization's network. Both types of SMTP relay play important roles in email communication and can be configured to meet different needs and security concerns.
