POP3

POP3 (Post Office Protocol Version 3) is the popular mail server protocol that accepts (receives) e-mail from a mail server. On some servers, IMAP4 (Internet Mail Access Protocol Version 4) is replacing POP3. Client-side programs such as Eudora and Microsoft Outlook can be used to receive email via POP3 or IMAP4. Some examples of POP3 server programs include Microsoft Exchange (on NT or Windows 2000) and sendmail (often seen on UNIX machines).

POP3

Know that POP3 and IMAP4 are for mail handling. POP3 uses port 110.
