NAME
       IPOPd - Post Office Protocol server

SYNOPSIS
       /usr/etc/ipop2d

       /usr/etc/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 to access mailboxes on IMAP servers by  specifying  a  login  user  name  in  the	form  <host>:<user>  e.g.,
       SERVER.WASHINGTON.EDU:SMITH.

       POPd  is  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)).

SEE ALSO
       imapd(8C)

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.
