Messaging Basics

Process

The Messaging server performs 2 basic roles:

1) Message Transfer Agent (MTA)

Accepts messages from clients and other servers, and transfers non-local messages to other servers, using the SMTP protocol. Delivers local messages into the users inbox folder in the local message store.


2) Message Access Agent

Allows local users client access to their stored messages, using either the POP3 or IMAP4 protocol.
