IMAP
From DreamHost
The Internet Message Access Protocol (commonly known as IMAP or IMAP4) is an application layer Internet protocol operating on port 143 that allows a local client to access email on a remote server. IMAP4 and POP3 are the two most prevalent Internet standard protocols for email retrieval. Virtually all modern email clients and servers support both.
