Mail Transfer Agent (MTA)

A Mail Transfer Agent (MTA) is software that handles the sending and routing of emails over the internet. Think of it as the postal service for digital messages—it determines where an email should go, transfers it between servers, and ensures it reaches the recipient’s mailbox. MTAs communicate with other MTAs using specific internet protocols to deliver messages reliably and securely. They play a crucial role in email delivery, coordinating the transfer from the sender’s email server to the recipient’s, ensuring your email reaches its destination efficiently.
