If that's the goal, no argument.  Microsoft will hopefully not control the
MUA market forever, so I was just looking to the future.  I am hoping that
either OpenOffice will one day produce an Outlook look-alike or that
Thunderbird will mature into a fully featured product competitive with
Outlook.  The Outlook plug-in is such a time-saver that it alone will keep
me on Outlook for a long time to come :)

I looked at
and it doesn't give any Tokenizer options at all, though they obviously
exist.  The directions also state that there are no experimental options in
this release.  Where else would I look to find a description of the
supported configuration options?

One of my email accounts also has a special header for Brightmail detected
spam that would be helpful to tokenize.  This is not the Brightmail tracker
header itself, but one that my ISP adds.  This header is always the same
text and is as follows:

X-TDS-Spam: Potential Spam

Is there any support for tokenizing special headers like this?  Could I
manually add this to the list of safe headers to tokenize with that option?

Sorry if I misinterpreted this.  I thought that Outlook passed you an
address string that contained some of the information between parentheses.
