<p>Il processo per portare una email da una persona a un'altra all'interno di una rete o attraverso internet, comporta l'utilizzo di diversi sistemi che cooperano tra loro. Ognuno di questi sistemi deve essere configurato correttamente. Colui che spedisce una email utilizza un <span class="emphasis"><em>Mail User Agent</em></span> (MUA), o client email, per spedire il messaggio attraverso uno o più <span class="emphasis"><em>Mail Transfer Agents</em></span> (MTA), l'ultimo dei quali lo consegnerà a un <span class="emphasis"><em>Mail Delivery Agent</em></span> (MDA) per la consegna nella casella di posta del destinatario, che la preleverà utilizzando un client email attraverso un server POP3 o IMAP.</p>
