Mail Transfer Agent

A Mail Transfer Agent (MTA) is software that helps send and receive email over the internet. When you send an email, the MTA takes your message and delivers it to the recipient's email server. It uses protocols, like SMTP (Simple Mail Transfer Protocol), to ensure your email reaches the right destination. MTAs also manage the routing of emails, handle errors, and can queue messages if the recipient's server is temporarily unavailable. Essentially, it's the behind-the-scenes system that ensures your emails travel smoothly from one address to another.
