4.23. dovecot

Updated dovecot packages that fix one bug are now available for Red Hat Enterprise Linux 5.
Dovecot is an IMAP server for Linux and other UNIX-like systems, primarily written with security in mind. It also contains a small POP3 server. It supports email in either the maildir or mbox format. The SQL drivers and authentication plug-ins are provided as sub-packages.

Bug Fix

Previously, the dovecot package contained a bug in the LDAP-related code and could get into an infinite loop when an LDAP connection was unstable, making it impossible for users to log in and read emails. This update fixes the LDAP code and dovecot now handles unstable connections with an LDAP server without problems.
Users of dovecot are advised to upgrade to these updated packages, which contain backported patches to fix this bug. After installing the updated packages, the dovecot service will be restarted automatically.
