1.1.1.3. FedoraΒΆ

Fedora is a Linux distribution that does not generally enforce a policy of not providing you with upgrades of software during the life-cycle of any of the distribution’s released versions, or what could otherwise be expected to constitute “stable”.

While package maintainers tend to want to prevent unpleasant surprises from being deployed to your Fedora system, and therefore generally ship only versions of one series to any one given released distribution version, the Cyrus project cannot guarantee you will not receive an upgrade at some point, and cannot guarantee this upgrade will run smoothly – even though we do our best.

To install the version of Cyrus IMAP that comes with the operating system, issue the following command for Fedora 18 or below:

# yum install cyrus-imapd cyrus-sasl cyrus-sasl-plain

or for Fedora 19 and above:

# dnf install cyrus-imapd cyrus-sasl cyrus-sasl-plain

Next, set a password for the default administrative user cyrus:

# passwd cyrus
Changing password for user cyrus.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.

Start and configure to start when the system boots, the saslauthd service. For Fedora 14 and below:

# service saslauthd start
Starting saslauthd:                                        [  OK  ]
# chkconfig saslauthd on

or for Fedora 15 and above:

# systemctl start saslauthd
# systemctl enable saslauthd

You should at this moment be able to authenticate against saslauthd:

# testsaslauthd -u cyrus -p YOUR-PASSWORD

You should get an 0: OK "Success." message.

Start the service, and ensure the service starts up when the system boots. For Fedora 14 and below:

# service cyrus-imapd start
# chkconfig cyrus-imapd on

or for Fedora 15 and above:

# systemctl start cyrus-imapd
# systemctl enable cyrus-imapd

You should now be able to login as the cyrus user, which is configured by default as an administrator for Cyrus IMAP:

# imtest -t "" -u cyrus -a cyrus localhost
