- has some defences against mail bombs and unsolicited junk mail in
- the form of options for refusing messages from particular hosts,
- networks, or senders. It can be installed in place of sendmail,

- <h2>New Things</h2>
- <ul>
- <li>
- An update to the system filter to protect broken MS mail
- clients from the real world has been produced. This protects
- against the bug described on <A HREF="http://www.securityfocus.com/frames/?content=/templates/article.html%3Fid%3D61">
- BugTraq</A> where a long date string can subvert the client.
- The filter can be found at <A HREF="ftp://ftp.exim.org/pub/filter/">
- <tt>ftp://ftp.exim.org/pub/filter/</tt></a> or
- <A HREF="system_filter.exim">here</A>. The file contains
- installation instructions.
- </li>
- <li>
- Exim Version 3.15 is available - see the <a
- href="mirrors.html">availability</a> pages to get hold of a
- copy.
- </li>
- <li>
- A <b>Generic Windows Executable Content</b> filter is available
- at <a href="ftp://ftp.exim.org/pub/filter/">
- ftp://ftp.exim.org/pub/filter/</a> . This is an exim system
- filter which attempts to detect executables including the
- types responsible for the recent Windows/Outlook mail worms.
- It is not infallible, but many sites may find it useful.

+ <h2>Current Versions</h2>
+ <p>
+ The current version of Exim is <b>4.34</b>. See the <a
+ href="mirrors.html"><b>Download</b></a> page to get a copy.
+ There were a number of issues with earlier <b>4.3x</b> versions
+ so their use is discouraged. Security fixes in this release
+ mean that all previous versions should be obsoleted in favour
+ of 4.34.
+ </p>
+
+ <p>Exim 3 and previous versions are now considered obsolete. Exim 3
+ is not being developed any further, nor is it being actively
+ maintained, though if a really serious bug were found, it would be
+ looked at.</p>
+
+ <p>The old system filter has been deleted from the site - it is
+ not appropriate for current mail configurations.</p>
