5.0 2005-07-16
    Major changes to the syntax of the config file. Content filtering
    is no longer a global mail server setting.

4.6 2005-04-02
    Fix enum compilation error on Fedora Core 3.
    Discovered by Nigel Horne <njh@bandsman.co.uk>

    Remove bad html tag command from the default conf file.  Spammers
    seem to have abandoned this.

    Add toolbar.msn.click-url.com in hosts-ignore.conf.  These are all
    commented, but you might want to uncomment them.

4.5 2005-01-22
    Add uuencode decoding for old style attachments.

4.4 2005-01-18
    Bug fix in forked process termination that left zombies.

4.3 2005-01-16
    Only keep 20% of the resolver sockets in the ready pool.

4.2 2005-01-08
    Use the separate resolver processes even if we don't have the
    resolver interfaces and need gethostbyname.

4.1 2005-01-06
    Use a local unix domain socket for the resolver process
    communication, rather than a tcp/ip socket.

4.0 2005-01-03
    Initialize the thread mutex objects early, before they are needed
    by possible calls to my_syslog.

    Fork off a separate resolver listener process, so we can do multiple
    dns operations in parallel. For each simultaneous inbound email,
    we have a separate sendmail process, a milter thread, and a dns
    resolver process.

3.7 2004-10-28
    Added an 'ignore' command to the conf file, used to ignore some
    hosts that might end up on the SBL and otherwise trip the content
    scanning filter.  In particular, many recent Microsoft Word
    documents contain the string www.5iantlavalamp.com which is
    associated with their smart tags stuff.  That is currently hosted at
    216.168.224.70, which is shared with a site that ended up on the
    SBL.

3.6 2004-09-08
    Contributions from Dan Harkless <software@harkless.org>
        Better documentation for disabling the content filtering.
        Don't bother looking at the body text if we are not doing
        content filtering.

3.5 2004-07-17
    Extend the error message for content filtering when the NS record
    points to an ip address on the SBL.  Include the original host name
    that referenced that NS name.


3.4 2004-07-15
    Tokens with two consecutive periods cannot be ip addresses or host
    names.

    Updated dnsbl.spec file for building rpms from John Gunkel.


3.3 2004-07-09
    Drop root priviledges properly, including the group id.


3.2 2004-07-09

    Contributions from John Gunkel <jgunkel@palliser.ca>:
        Add .spec file for building rpms, contributed by John Gunkel

        Changes to file layout to conform to RedHat/LSB standards.

        Add some html (actually xml) tags used by Apple mac print
        subsystem that were tripping the html tag detector.

        Help with changes required to allow dnsbl to drop root
        priviledges. Move the socket to /var/run/dnsbl/dnsbl.sock

    Change parser to handle &#xnnn; obfuscated urls with charaters
    specified in hex.

    Make bad_html tags more sensitive to binary tags, to reduce false
    positives in .zip or .tar.gz file attachments.

    Add sendmail queueid to the dnsbl syslog messages.

    Fix one place where host names were not forced to lower case.
    Discovered by Nigel Horne <njh@bandsman.co.uk>

    Remove duplicate dns queries within the same smtp transaction from
    the body content filtering.  This helps if the mail server does not
    have a nearby caching dns server.

    Add host_soft_limit config keyword.  Use only one of host_limit or
    host_soft_limit, since the last one wins.  The host_limit is a hard
    upper limit on the number of host names in a message.  The
    host_soft_limit allows unlimited host names, but only checks a
    random sample of them against the dnsbl.

    The main thread has dropped root priviledges, but other threads
    are still running as root. This needs to be fixed.
