Managing IMAP

Getting Cyrus Up and Running

Edit /etc/services, if necessary, to contain the following line:

imap    143/tcp

Edit /etc/inetd.conf to include the line:

imap stream tcp nowait cyrus /usr/cyrus/bin/imapd imapd

Once the files have been edited, restart inetd. On most Unix systems, find the process ID, then send a HUP signal to the process using the kill command:

#ps –ef | grep inetd
root 13005    1  0 22:50:57 ? 0.00    0:00 /usr/sbin/inetd –s
# kill –HUP 13005

If your Unix supports the pkill command, then you can save a step by using the command:

#/usr/bin/pkill –HUP –x inetd

Testing a Cyrus Installation on the Same Machine as Your Production Server

If you are currently running an IMAP server and wish to test a Cyrus installation without disabling the current IMAP server, specify an alternate name and port in /etc/services, such as:

imaptest 243/tcp

Add the following line to /etc/inetd.conf :

imaptest stream tcp nowait cyrus /usr/cyrus/bin/imapd imapd

After restarting inetd, the imaptest server will be running on port 243. Switching from the old to the new server is a simple matter of changing the name of the imaptest service in /etc/inetd.conf to imap and restarting inetd.

Caution is advised: the test server should never modify files that belong to the production server. Configure your test server’s imapd.conf to use a different set of configuration files and a different mailstore than your production server uses.
