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)).

BUGS

       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.
