A new version of the alternate C implementation of SPF (libspf-alt) is
now available at:
http://www.midwestcs.com/spf/libspf-alt
Version 0.3 is mostly a bug-fix release.
The major highlights of this release are:
* Most of the work was directed toward the new SPF test system and
making libspf-alt pass as many of the tests as practical.
* Quite a bit of documentation was added to the include files. While
still far from production quality documentation, you should no
longer have to dig through lots of source code in order to figure
out what is going on.
* IPv6 is not supported, making libspf-alt the first SPF
implementation to do so. Testing, however, has been limited.
* A new 'zone' DNS layer has been created. This allows you to create
internal 'zone files' that will override or create fallbacks for
other domains that don't currently publish SPF records. Unlike the
perl M:S:Q 1.996 override/fallback options, the libspf-alt 'zone'
DNS layer can also create SPF explanation records or any other DNS
entry that you find useful.
The zone DNS layer can also be used for things like marking sections
of the rDNS tree as not resolvable, thus instantly returning the
results, instead of waiting for all those name servers to timeout.
* The caching DNS layer has been made more useful in several ways.
* The cache can now support more than 64k entries
* The cache now has a small reclaim-list to reduce the cost of hash
collisions.
* You can now set minimum Time To Live (TTL) values
* min_ttl The absolute minimum TTL value in all cases.
* err_ttl The minimum TTL value to use when there is a DNS error.
* txt_ttl The minimum TTL value to use when a TXT query is done.
In the case of SPF, these are the SPF records and the
explanation records. This TTL value is used even when
no record is found, so domains that haven't set up SPF
records won't be constantly queried.
* rdns_ttl The minimum TTL value to use when looking up information
in the reverse DNS tree.
Comments, suggestions, bug reports, and complaints, are welcome!
