MTA (Mail Transfer Agent) is responsible for relaying mail between mail servers. It is designed to handle mail delivery between different hosts on the internet and can route mail across networks. MTA typically relays mail for one application-level hop, which means that it delivers mail to another MTA or to a Mail Delivery Agent (MDA) that handles the delivery of mail to the recipient's mailbox. MS (Mail Server) is a general term that refers to any server that handles email, including both MTAs and MDAs. POP (Post Office Protocol) is a protocol used by email clients to retrieve mail from a mail server. MSA (Mail Submission Agent) is responsible for accepting mail from email clients and relaying it to an MTA or MDA.
