> The following problems were fixed with the Postfix legacy releases:
> 
>     * Fix for CVE-2011-0411: discard buffered plaintext input,
>       after reading the SMTP "STARTTLS" command or response.  
> 
>     * Fix to the local delivery agent: look up the "unextended"
>       address in the local aliases database, when that address has
>       a malformed address extension.  
> 
>     * Fix to virtual alias expansion: report a tempfail error,
>       instead of silently ignoring recipients that exceed the
>       virtual_alias_expansion_limit or the virtual_alias_recursion_limit.
> 
>     * Fix for Solaris: the Postfix event engine was deaf for SIGHUP
>       and SIGALRM signals after the switch from select() to /dev/poll.
>       Symptoms were delayed "postfix reload" response, and killed
>       processes with watchdog timeout values under 100 seconds.
> 
>     * Fix for HP-UX: the Postfix event engine was deaf for SIGALRM
>       signals. Symptoms were killed processes with watchdog timeout
>       values under 100 seconds.  
> 
>     * Fix for BSD-ish mkdir() to prevent maildir directories from
>       inheriting their group ownership from the parent directory.
> 
>     * Fix to the SMTP client: missing support for mail to
>       [ipv6:ipv6addr] address literal destinations.  
> 
>     * FreeBSD back-ported closefrom() from FreeBSD 8x to 7x, breaking
>       Postfix builds retroactively.

> Historical note:
> 
>     Wietse Venema discovered the problem two weeks before the
>     Postfix 2.8 release, and silently fixed it pending further
>     investigation. While investigating the problem's scope and
>     impact, Victor Duchovni found that many other TLS applications
>     were also affected. At that point, CERT/CC was asked to coordinate
>     with the problem's resolution.
