POP3

**Post Office Protocol 3**
POP3 is a version of a protocol for recieving e-mail. POP3 is a client/server protocol where e-mail is recievied and held by your mail server. When you load up your e-mail you are connecting to the mail server which the downloads the e-mail from its server to your hard drive.

POP3 is designed to delete mail on its server as soon as you have downloaded it onto your hard drive. But however if you are an administrator or if you can, you can ask for mail to be saved for a chosen lenght of time. Therefore POP is somtimes reffered to as a "store-and-forward" service. A POP3 server uses well-known port 110.

The most common POP3 email manager available is Microsoft Outlook. Microsoft Outlook is a personal information manager from Microsoft, available both as a separate application as well as a part of the Microsoft Office suite. The current version is Microsoft Office Outlook 2010 for Windows and Microsoft Office Outlook 2011 for Mac.
