RHBA-2011:1075 - Bug Fix Advisory

Topic

Updated cyrus-imapd packages that fix multiple bugs are now available for Red
Hat Enterprise Linux 5.

Description

The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3,
NNTP and SIEVE support.

This update fixes the following bugs:

• Prior to this update, cyrus-imapd cleared its back end before

deinitialization. As a result, when the "unselect" command was used in proxy
mode, cyrus-imapd terminated unexpectedly. This bug has been fixed in this
update so that cyrus-imapd now clears the back end after deinitialization, and
the "unselect" command can be used properly in proxy mode as expected.
(BZ#679253)

• Prior to this update, the "ignorequota" command did not work on 64-bit

systems. As a result, despite using the "ignorequota" command, it was not
possible to deliver a mail message to a user whose quota exceeded the quota
limit. This bug has been fixed in this update so that the "ignorequota" command
now works on 64-bit systems, as expected. (BZ#584088)

• Prior to this update, Python files included in the cyrus-imapd packages

contained the "#!/usr/bin/env python" string. With this update, the string in
the aforementioned files has been modified to "#!/usr/bin/python" so that
another version of Python can now be installed as expected. (BZ#521338)

• Prior to this update, the cyrus-imapd packages required the lm_sensors-devel

package at build time. The lm_sensors-devel package is not available on all
platforms supported by Red Hat Enterprise Linux 5. As a result, a very complex
spec file had to be distributed with the cyrus-imapd packages. With this update,
this bug has been fixed in this update so that the cyrus-imapd packages now
require only the net-snmp-devel package, which already solves the lm_sensors
package requirement. (BZ#437999)

• Prior to this update, cyrus-imapd did not close all file descriptors that were

used for quota. As a result, after moving several folders, cyrus-imapd could
have used up available file descriptors and could have not been able to function
properly. With this update, cyrus-impad now closes all quota descriptors when
they are no longer required, as expected. (BZ#253854)

All users are advised to upgrade to these updated cyrus-imapd packages, which
fix these bugs.
