- SMTP isn't so restricted. You can send and recieve email to/from ANY
- server anywhere on the internet; no password required.

- SMTP & POP are meant to solve different problems.
-
- SMTP is a Mail Transport system. It's designed for moving Mail around
- the network. It was designed in the good old days when everyone who
- had the tools and knowledge to forge email had reasons for not wanting
- mail forgery to work. It's primarily used for sending mail between
- peer computers of various kinds. High-end implementations don't ever
- depend on some other computer to touch the mail, unless there is data
- in the internet-wide hosts database (DNS) instructing it to do so.
-
- POP is a Post Office Protocol. A host in the SMTP peer network acts
- like a post office - it collects mail from other SMTP hosts on the
- internet and holds it until the POP client comes to collect it.
- Likewise, it will accept mail from POP clients for delivery elsewhere
- on the internet. Since POP was designed for use in hostile
- environments (your local university network, for instance) it includes
- user identification and authorization features. POP (2; I haven't
- checked 3) always depend on talking to an intermediate host that is
- filling the role of the Post Office to deliver mail. From the above,
- it appears that POP3 can deal with multiple mail servers and use any
- of them as the gateway if required.
