ipopd(1M)


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. They 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, for example SERVER.WASHINGTON.EDU:SMITH.

popd is normally invoked by the Internet server (see the inetd(1Mtcp) manual page) for requests to connect to the POP port as indicated by the /etc/services file (see the services(4tcp) manual page).

The POP2 and POP3 protocols are intrinsically less flexible than IMAP (see the imapd(1M) manual page) and do not maintain ``read'' vs ``unread'' states 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.
