NAME
IPOPd - Post Office Protocol server
SYNOPSIS
/usr/sbin/ipop2d
/usr/sbin/ipop3d
DESCRIPTION
ipop2d
and
ipop3d
are servers which support the
POP2
and
POP3
remote mail access protocols respectively.
ipop2d
and
ipop3d
can also be used by
POP2
and
POP3
clients respecitively to access mailboxes on
IMAP
servers by specifying a login user name in the form <host>:<user>
e.g.,
SERVER.WASHINGTON.EDU:SMITH.
These daemons contain CRAM-MD5 and APOP support. See the md5.txt
documentation file for additional information.
ipop2d
and
ipop3d
are invoked by the internet server (see
inetd(8)),
normally for requests to connect to the
POP
port as indicated by the
/etc/services
file (see
services(5)).
The
POP2
and
POP3
protocols are intrinsically less flexible than
IMAP
and do not maintain `read' vs `unread' state on the server. As a result,
most
POP
based software transfers all the mail from the server to the client and
deletes it from the server. This necessarily locks the user into using only
a single client.
POP3
does not allow you to specify an alternate folder from the user's default.
