Here is a basic run down.
The Post Office Protocol - Version 3 (POP3) is intended to permit a workstation to dynamically access a maildrop on a server host in a useful fashion. Usually, this means that the POP3 protocol is used to allow a workstation to retrieve mail that the server is holding for it.
POP3 is not intended to provide extensive manipulation operations of mail on the server; normally, mail is downloaded and then deleted. A more advanced (and complex) protocol, IMAP4, is discussed in [RFC1730].
AnswerA POP mail server (or simply "POP server") is the most common form of incoming email server. Basically, the POP server is what receives the email and is almost always used with an SMTP server, which is the outgoing server. The best way to find out the address of your POP server is to ask the company who is providing your email service. You will need to know this information if you are planning to set up an email client such as Thunderbird, Outlook, or Eudora to access your email. AnswerPOP (Post Office Protocol) mail client programs (e.g., Eudora, Netscape Communicator, Microsoft Exchange, Microsoft Outlook) allow you to retrieve your e-mail from the central server to your local computer. When someone sends you an e-mail message, the message is received, processed and stored in your mail file on the central mail server (for most this is slate).You can access your e-mail: 1) locally by logging onto the mail server and using a mail client program (e.g., "pine" or "elm"); or 2) remotely by using a POP/IMAP client program. With a POP client your e-mail is copied/retrieved from the mail server to a local computer. With an IMAP client your e-mail is accessible remotely, but is stored and managed on the server. (A subset of POP e-mail client programs also function as IMAP clients. The advantages and disadvantages of POP vs IMAP are discussed in the "Electronic Mail Quick Reference" guide. IMAP configuration is discussed in the "IMAP Quick Reference" guide.)
Incoming mail that you receive from other people can only be downloaded to your email client if you're using the right Mail.com POP3 or IMAP server settings. To download mail from your Mail.com account to your email program, use the correct POP3 or IMAP server settings for Mail.com.
Mail.com POP3 Server SettingsIncoming mail server (POP3): pop.mail.Yahoo.com
Outgoing mail server (SMTP): smtp.mail.yahoo.com
POP is a protocol that allows a user to access their email through third party site or service. POP is an alternative to IMAP or Microsoft exchange.
Yes it is, I use POP3 through sbcglobal from Outlook Express and Linux's Thunderbird.
MSN account does not support POP3 or IMAP server. these accounts work with http server.
Mail.comcast.net
In the Incoming mail (POP3, IMAP, or HTTP) server box, type pop3.live.com. In the Outgoing mail (SMTP) server box, type smtp.live.co
Hotmail's incoming mail server for POP3 is pop3.live.com on port 995. Hotmail's incoming mail server for IMAPis imap-mail.live.com on port 993.
pop.yahoo.com smtp.yahoo.com I think
CAS
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.
the new incoming server is: pop3.live.com Out going server is: smtp.live.comThe Windows Live POP3 mail server settings are:• pop3.live.com - for the Incoming mail• smtp.live.com - for the Outgoing mail
POP3 and IMAP4
Verizon just added ssl encryption to it's POP3 servers. They have been phasing it in over the past 6 months (as of January, 2012). Incoming Server: incoming.verizon.net - port 995 Outgoing Server: outgoing.verizon.net - port 465
Hotmail does not support pop3 unless you are a paying subscriber. GMX.com is free mail that does support pop3 and imap.
