SYNOPSIS

DESCRIPTION

14       ipop2d  and  ipop3d  are servers which support the POP2 and POP3 remote
15       mail access protocols respectively.  ipop2d and ipop3d can also be used
16       by  POP2  and  POP3  clients  respecitively to access mailboxes on IMAP
17       servers by specifying a login user name in the form <host>:<user> e.g.,
18       SERVER.WASHINGTON.EDU:SMITH.
19
20       These daemons contain CRAM-MD5 and APOP support.  See the md5.txt docu‐
21       mentation file for additional information.
22
23       ipop2d and ipop3d are invoked by the internet  server  (see  inetd(8)),
24       normally  for  requests  to connect to the POP port as indicated by the
25       /etc/services file (see services(5)).

BUGS

31       The POP2 and POP3 protocols are intrinsically less flexible  than  IMAP
32       and  do  not  maintain  `read'  vs  `unread' state on the server.  As a
33       result, most POP based software transfers all the mail from the  server
34       to  the  client and deletes it from the server.  This necessarily locks
35       the user into using only a single client.
36
37       POP3 does not allow you to specify an alternate folder from the  user's
38       default.
