IMAP Installation and Initial Configuration

First, we grab the source from the UW distribution link on here:

[root@srv-33 src]# ls
imap.tar.Z  imap-utils.tar.Z
[root@srv-33 src]# tar -xzf imap.tar.Z
[root@srv-33 src]# ls
imap-2001.BETA.SNAP-0105251616  imap.tar.Z  imap-utils.tar.Z
[root@srv-33 src]# mkdir imaputils

(We will deal with imaputils in a different section.)

[root@srv-33 src]# mv *util* imaputils
mv: cannot move `imaputils' to a subdirectory of itself, `imaputils/imaputils'
[root@srv-33 src]# ls
imap-2001.BETA.SNAP-0105251616  imap.tar.Z  imaputils
[root@srv-33 src]# cd imap-2*
[root@srv-33 imap-2001.BETA.SNAP-0105251616]# make slx

[root@srv-33 imapd]# cp imapd /usr/local/sbin/imap

Now, we need to start these services automatically. For Red Hat, we just add ipop2d, ipop3d, and imapd to /etc/xinetd.d:

[root@srv-33 xinetd.d]# cat ipop2d
# default: on
# description: The pop server answers pop requests.
service pop2
{
socket_type     = stream
wait            = no
user            = root
server          = /usr/local/sbin/ipopd/ipop2d
disable         = no
}
[root@srv-33 xinetd.d]# cat ipop3d
# default: on
# description: The pop3 server answers pop3 requests.
service pop3
{
socket_type     = stream
wait            = no
user            = root
server          = /usr/local/sbin/ipopd/ipop3d
disable         = no
}
[root@srv-33 xinetd.d]# cat imapd
# default: on
# description: The imap server answers imap requests.
service imap
{
socket_type     = stream
wait            = no
user            = root
server          = /usr/local/sbin/imapd/imapd
disable         = no
}
[root@srv-33 xinetd.d]#

Notice that we are starting both pop and imap services. The danger with pop is that users can download all of their mail locally, where it won’t get backed up. Since some of you may prefer the flexibility of pop, we are going to include installation of pop in these intructions. Let’s make sure all is good and the services start up after we reboot.

Setting up IMAP on the client side is quite easy. With Star Office, Netscape, and Outlook, you simply specify the name of the IMAP server and the user account. It really is that easy. Let’s send email to u-1:

[root@srv-33 /root]# mail u-1
Subject: test 2 u-1
this is a test of IMAP
Cc:
[root@srv-33 /root]#

Here we see the email show up in Outlook, as well as the configuration dialog boxes.

If you want to check this with Pine, just edit .pinerc in your home directory so that inbox-path points to the correct IMAP server (inbox-path={srv-33}inbox), then, simply run Pine, and you can check your mail:

PINE 4.33   MESSAGE TEXT               Folder: INBOX  Message 4 of 4 ALL NEW
Date: Thu, 31 May 2001 08:24:35 -0700

All is happy.
