Какого это RFC? ;-) Смотрим RFC 1939:
8. Scaling and Operational Considerations
* Enforce a site policy regarding mail retention on the server.
Sites are free to establish local policy regarding the storage and
retention of messages on the server, both read and unread. For
example, a site might delete unread messages from the server after
60 days and delete read messages after 7 days. Such message
deletions are outside the scope of the POP3 protocol and are not
considered a protocol violation.
Server operators enforcing message deletion policies should take
care to make all users aware of the policies in force.
Clients must not assume that a site policy will automate message
deletions, and should continue to explicitly delete messages using
the DELE command when appropriate.
It should be noted that enforcing site message deletion policies
may be confusing to the user community, since their POP3 client
may contain configuration options to leave mail on the server
which will not in fact be supported by the server.
Как видно, явно сказано "are not considered a protocol violation".
Смотрим свежий (и, на самом деле, слегка кривой) RFC 2449:
6.7. EXPIRE capability
CAPA tag:
EXPIRE
Arguments:
server-guaranteed minimum retention days, or NEVER; optionally
followed by USER in AUTHENTICATION state
[...]
Discussion:
While POP3 allows clients to leave messages on the server, RFC
1939 [POP3] warns about the problems that may arise from this,
and allows servers to delete messages based on site policy.
The EXPIRE capability avoids the problems mentioned in RFC 1939,
by allowing the server to inform the client as to the policy in
effect. The argument to the EXPIRE capability indicates the
minimum server retention period, in days, for messages on the
server.
EXPIRE 0 indicates the client is not permitted to leave mail on
the server; when the session enters the UPDATE state the server
MAY assume an implicit DELE for each message which was downloaded
with RETR.
EXPIRE NEVER asserts that the server does not delete messages.
Ну и так далее, с подробностями.
