Sending messages: User Agent (the user's mail composing program) is a client of a local SMTP server and passes each outgoing message to the SMTP server for delivery.
Reading messages: User Agent (the user's mail reading program) is either a client of the local file server or a client of a mail delivery server such as a POP or IMAP server.
In the former case, the User Agent reads messages directly form the mailbox file in which they were placed during the message delivery.
(Exampes of such user agents are the UNIX mail and pine commands.)
In the latter case, the User Agent requests information about the contents of the user's mailbox file from a POP or IMAP server and receives messages from those servers for presentation to the user.
