SMTP Vs POP3

* SMTP - Simple Mail Transfer Protocol o Standard mechanism by which outgoing mail is delivered on the Internet + Incoming E-mail messages are held on the server until it is called for by the user. POP governs the transaction. * POP3 - Post Office Protocol, Version 3 o POP3 host: Machine where account you wish to access is located o Mail can be accessed (received) with a POP3 client

SMTP which stands for Simple Mail Transfer Proctocol is for sending your email. POP3 which I have no idea what stands for is for recieveing your email I believe that the division is for Routing purposes but am not sure to be honest
