POP3

Version 3 of the {Post Office Protocol}.

POP3 is defined in {RFC 1081}, written in November 1988 by

Marshall Rose, which is based on RFC 918 (since revised as RFC

937). POP3 allows a {client} computer to retrieve {electronic

mail} from a POP3 {server} via a (temporary) {TCP/IP} or

other[?] connection. It does not provide for sending mail,

which is assumed to be done via {SMTP} or some other method.

POP is useful for computers, e.g. mobile or home computers,

without a permanent network connection which therefore require

a "post office" (the POP server) to hold their mail until they

can retrieve it.

Although similar in form to the original POP proposed for the

{Internet} community, POP3 is similar in spirit to the ideas

investigated by the {MZnet} project at the University of

California, Irvine, and is incompatible with earlier versions

of POP.

Substantial work was done on examining POP in a {PC}-based

environment. This work, which resulted in additional

functionality in this protocol, was performed by the {ACIS}

Networking Systems Group at {Stanford University}.

RFC 1082 (POP3 Extended Service) extends POP3 to deal with

accessing mailboxes for {mailing lists}.
