Updated cyrus-imapd packages that fix one bug are now available for Red Hat Enterprise Linux 6.
The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and SIEVE support.
- Previously, the idled daemon incorrectly used signals for communication with the imapd daemon. This could cause a user's mailbox to become unresponsive. To prevent this problem, idled no longer uses signals to communicate with imapd; the AF_UNIX datagram sockets are now used instead.
All users of cyrus-imapd are advised to upgrade to these updated packages, which fix this bug.
