You see, there are Protocols called HTTP and POP.
HTTP stands for Hyper Text Transfer Protocol
while,
POP stands for Post Office Protocol.
These two sets of Rules enable server to identify that who sent the email to whom. HTTP is responsible to maintain the format of the Email, while POP helps server
Most email clients use one of three protocols to receive an email message. They are SMTP (Simple Mail Transfer Protocol), POP (Post Office Protocol), or IMAP (Internet Message Access Protocol).
IMAP supports both connected and disconnected modes of operation. E-mail clients using IMAP generally leave messages on the server until the user explicitly deletes them. This and other facets of IMAP operation allow multiple clients to access the same mailbox. Most e-mail clients support either POP3 or IMAP to retrieve messages; however, fewer Internet Service Providers (ISPs) support IMAP. IMAP4 offers access to the mail store; the client may store local copies of the messages, but these are considered to be a temporary cache; the server's store is authoritative. E-mail messages are generally sent to an e-mail server that stores received messages in the recipient's e-mail mailbox. The user later retrieves these messages with either a web browser or an e-mail client that uses one of a number of e-mail retrieval protocols. While some clients and servers preferentially use vendor specific, typically proprietary protocols, most support the Internet standard protocols SMTP for sending e-mail and POP3 and IMAP4 for retrieving e-mail, allowing interoperability with other servers and clients. For example, Microsoft's Outlook client typically uses a proprietary protocol to communicate with an Exchange server as does IBM's Notes client when communicating with a Domino server, but all of these products also support SMTP, POP3, and IMAP4. Support for the Internet standard protocols allows many other e-mail clients such as Qualcomm's Eudora or Mozilla Thunderbird (see comparison of e-mail clients) to access these servers and similarly allows the clients to be used with other servers (see list of mail servers). E-mail clients can generally be configured to use either POP3 or IMAP4 to retrieve e-mail and in both cases use SMTP for sending. Most e-mail programs can also use Lightweight Directory Access Protocol (LDAP) for directory services. Nearly all subscribers to individual Internet service provider e-mail accounts access their e-mail with client software that uses POP3.[citation needed] IMAP is often used in large networks; for example, a college campus mail system. IMAP allows users to access new messages instantly on their computers, since the mail is stored on the network. With POP3, users either download the e-mail to their computer or access it via the web. Both methods take longer than IMAP, and the user must either download any new mail or "refresh" the page to see the new messages.
it doesnt
No. The POP3 protocol is a network protocol. It is only concerned with the messages sent back and forth between the mail server and the mail client. The internal format of the mailbox files on the server is only of concern to the POP3 server software. It needs to be able to read the mailbox files so it can send the proper messages to the POP3 client in order to transfer the email. HTH, Gdunge

POP is Post Office Protocol. It is a protocol used by email clients to retrieve emails from a remote server.
Email clients are programs intended to access remote mail servers and retrieve mail from them. Email clients allows also to compose and send email messages. Email client is a perfect solution for dial-up connection, since the messages can be viewed without an Internet connection. But there are much more email clients that are worth mentioning. Web based email clients gained great popularity among the Internet users. The main disadvantage of the web-based mail is that is the lack of offline capability.
IMAP4 and POP3
i have incredimail(att) and it lets me do all that
From milliseconds to a few minutes, depending on the DNS servers between your email server and the email server of your recipient
Server act as a virtual post office for email. It stores emails that you send to other person until he retrieve it.
Post Office Protocol version 3 (POP3) is a protocol used by email clients to retrieve emails from a mail server. It operates on port 110 and typically downloads emails from the server to the client's device.
Most email clients use one of three protocols to receive an email message. They are SMTP (Simple Mail Transfer Protocol), POP (Post Office Protocol), or IMAP (Internet Message Access Protocol).

If it's on a server you should just be able to log in. They should offer dirrections once logged in.
