IPOPD(8C)IPOPD(8C)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.

imapd - Internet Message Access Protocol (IMAP) server process
SYNOPSIS
/usr/sbin/imapd
DESCRIPTION
The IMAP4rev1 server, imapd, accepts commands on its standard input and responds on its standard output. It is normally invoked by the
inetd command and it reads its configuration options out of the imapd.conf file.
If you want to take the IMAP server off line for a period of time, you should notify the client systems. To do this, create a msg/shutdown
file, edit it, and state the reason for the shut down. Set the owner of the msg directory and the shutdown file to be the imap user. When
a client system tries to access the server, imapd sends the first line contained in the shutdown file to the client and closes the connec-
tion.
If you want to send a message to the IMAP clients without disabling connections, create a msg/motd file, edit it, and add your message.
Set the owner of the msg directory and the motd file to be the imap user. The server sends the first line contained in the file to the
clients upon connection as an ALERT message, which IMAP-compliant clients are required to display. Access to mailboxes is unaffected.
For debugging purposes, create a log/user directory. When this directory exists, the imapd daemon creates protocol telemetry logs for ses-
sions authenticating as user. The telemetry logs are stored in the log/user directory with the file name of the imapd process id.
The msg/shutdown and msg/motd files and the log/user directory should be created under the directory specified in the configdirectory con-
figuration option of the imapd.conf file. The default value is /var/imap, as in /var/imap/msg/motd.
