+0. Release history
+==================
+
+2006-01-19	internal review draft
+
+
+1. Background
+=============
+
+fetchmail is a software package to retrieve mail from remote POP2, POP3,
+IMAP, ETRN or ODMR servers and forward it to local SMTP, LMTP servers or
+message delivery agents.
+
+fetchmail ships with a graphical, Python/Tkinter based configuration
+utility named "fetchmailconf" to help the user create configuration (run
+control) files for fetchmail.
+
+
+2. Problem description and Impact
+=================================
+
+Fetchmail contains a bug that causes itself to crash when bouncing a
+message to the originator or to the local postmaster. Fetchmail crashes
+when trying to free the dynamic array of failed addresses, and calls the
+free() function with an invalid pointer.
+
+Note that such messages are not RFC-822 conformant, so if the server has
+not been tampered with, the server software is faulty.
+
+
+3. Workaround
+=============
+
+None known at this time.
+
+
+4. Solution
+===========
+
+Download and install fetchmail 6.3.2 or a newer stable release from
+fetchmail's project site at
+<http://developer.berlios.de/project/showfiles.php?group_id=1824>.
+
+
+5. End of life announcement
+===========================
+
+The aged fetchmail 6.2.5.X branch is discontinued effective immediately.
+No further releases from the 6.2.5.X branch will be made.
+
+The new 6.3.X stable branch has been available since 2005-11-30
+and will not change except for bugfixes, documentation and translations.
