Abstract

[POP3] is a widely-deployed mail access protocol. Many programs access POP3 message stores, and thus need POP3 configuration information. Since there are multiple configuration elements which are required in order to access a mailbox, a single string representation is convenient.

1. Introduction

[POP3] is a widely-deployed mail access protocol. Many programs

access POP3 message stores, and thus need POP3 configuration

information. Since there are multiple configuration elements which

are required in order to access a mailbox, a single string

representation is convenient.

A POP3 mailbox (like an [IMAP4] mailbox) is a network resource, and

URLs are a widely-supported generalized representation of network

resources.

A means of specifying a POP3 mailbox as a URL will likely be useful

in many programs and protocols. [ACAP] is one case where a string

encapsulation of elements required to access network services is

needed. For example, an [IMAP4] message store is usually specified

in ACAP datasets as an [IMAP-URL].

This memo defines a URL scheme for referencing a POP mailbox.

2. Conventions Used in this Document

The key words "MUST", "MUST NOT", "SHOULD", "SHOULD NOT", and "MAY"

in this document are to be interpreted as defined in "Key words for

use in RFCs to Indicate Requirement Levels" [KEYWORDS].

3. POP Scheme

The POP URL scheme designates a POP server, and optionally a port

number, authentication mechanism, authentication ID, and/or

authorization ID.

The POP URL follows the common Internet scheme syntax as defined in

RFC 1738 [BASIC-URL] except that clear text passwords are not

permitted. If : is omitted, the port defaults to 110.

The POP URL is described using [ABNF] in Section 8.

A POP URL is of the general form:

pop://;auth=@:

Where , , and are as defined in RFC 1738, and some

or all of the elements, except "pop://" and , may be omitted.

4. POP User Name and Authentication Mechanism

An authorization (which mailbox to access) and authentication (whose

password to check against) identity (referred to as "user name" for

simplicity) and/or authenticatio...
