Well, there is an X-IMAPbase header in the first message, but it does not 
seem to change when I diddle with Thunderbird's labels.

So, before I did anything, with thunderbird closed:

-----
gruizade at csefast(pts/0):~ 49 > echo $MAIL
/var/spool/mail/gruizade
gruizade at csefast(pts/0):~ 50 > cp $MAIL inbox.backup
`/var/spool/mail/gruizade' -> `inbox.backup'
gruizade at csefast(pts/0):~ 51 > diff inbox.backup $MAIL
-----

That diff verified that my copy is the same as my inbox.

Then I opened thunderbird, and applied $Label1 through $Label5 to the first 
five messages, respectively.  I then told Thunderbird to compact all 
folders, and then quit.  Then I tried to see what changed:

-----

Diff told me, sadly, that nothing changed in my inbox.  Thunderbird, though, 
seems to think the messages are still tagged, which leads me to believe the 
tagging is somehow cached either in Thunderbird, or somewhere else.  I have 
no idea where that somewhere else would be, though, because Thunderbird on 
_another_ machine will pick up the labels, but no idea from where!

Both before and after I applied the labels, my X-IMAPbase header looked like:

X-IMAPbase: 1129222811 0000045702 $NotJunk JunkRecorded NonJunk $Label3 Junk 
$Label1 $Label2 $Label4 $Label5

It only seems to change when messages are added or removed from the inbox, 
and the only part that changes is the second number (last UID?)  As messages 
are read, Status and X-UID headers are added/updated properly, though.

Here's the session:

-----

Looking in the mailbox after this test, there is indeed an X-Keywords header:

X-Keywords: test

Yet, no matter which Thunderbird I try to use, on which platform, this 
doesn't happen.

So, I'm really confused now.
