SMTP servers are characterized by their simplicity and efficiency. They follow a set of standardized rules and protocols to ensure that email messages are properly formatted, routed, and ultimately delivered. These servers handle various tasks, including:

Message Queueing: SMTP servers efficiently queue and manage outgoing messages, ensuring that they are dispatched in the correct order and without overwhelming the system.

Address Resolution: SMTP servers are responsible for translating human-readable email addresses into machine-readable IP addresses, facilitating accurate message routing.

Reliability and Error Handling: SMTP servers incorporate mechanisms to handle temporary errors (such as network congestion) and to retry message delivery until successful transmission or a final failure status is received.

Authentication and Security: Modern SMTP servers implement security measures like authentication (to prevent unauthorized usage) and encryption (to protect message content from eavesdropping).
