Overview
This memo is a revision to RFC 1225, a Draft Standard. It makes the
following changes from that document:
- the RPOP facility is removed;
- the optional APOP facility is added (which is in interoperable,
operational use in at least three implementations);
- a typo was corrected with respect to the interaction of LAST
and RSET;
- section numbers were added; and,
- an acknowledgements section was added.
1. Introduction
On certain types of smaller nodes in the Internet it is often
impractical to maintain a message transport system (MTS). For
example, a workstation may not have sufficient resources (cycles,
disk space) in order to permit a SMTP server [RFC 821] and associated
local mail delivery system to be kept resident and continuously
running.
Similarly, it may be expensive (or impossible) to keep a personal
computer interconnected to an IP-style network for long amounts of
time (the node is lacking the resource known as "connectivity").
Despite this, it is often very useful to be able to manage mail on
these smaller nodes, and they often support a user agent (UA) to aid
