How does SMTP relay work?

SMTP, or Simple Mail Transfer Protocol, relay is a process that allows email messages to be transmitted across different networks. It works by relaying messages between email servers, rather than sending them directly from the user's computer to the recipient's server. When a user sends an email, the message is first transmitted to their outgoing mail server, also known as the SMTP server. The SMTP server then relays the message to the recipient's incoming mail server through a series of hops across different servers until it reaches its final destination. SMTP relay is commonly used by businesses and organizations to ensure reliable and efficient email delivery. It also allows for more control over email communication by managing spam filtering and monitoring outgoing email traffic.
