Mail::SPF::Query version 1.992 has been released; it fixes a couple of
minor bugs and adds support for "fallback" and "override" functionality.

"fallback" lets you pretend a domain has an SPF record.

"override" lets you override a domain's existing SPF record.

Mail::SPF::Query version 1.993 has been released; it adds support for
Caller-ID lookups. You will need Expat, XML::Parser, and LMAP::CID2SPF
from http://www.baschny.de/spf/LMAP-CID2SPF-0.9.tar.gz (note that the
CID2SPF module name may change in the future; experiment at your own risk.)

Caller-ID may be a patented technology and you may require a license
from Microsoft to use it. If this worries you, you should download
version 1.992 instead.

Much of Caller-ID's mail server declaration syntax can be translated
into a subset of SPF. Caller-ID is described in detail at
http://www.microsoft.com/mscorp/twc/privacy/spam_callerid.mspx

The following output demonstrates a lookup against Hotmail.com.

I have this to say:

And I really hate to be the one to say it, but also this:

Confucious has been heard to have said that pictures are worth a
