I haven't used any other MUA for years, so I don't know how they do their
searches.  However, it doesn't make technical sense to perform a full body
search in the MUA since all the body data is typically left on the IMAP server.
 This would make the search horribly slow over dsl/cable and generate a ton of
useless network traffic.  On a local network it would be much faster, but again,
it would generate a ton of useless traffic.  Body searches should always be
performed by the IMAP server itself.

You misread what I sent.  My comment relating to about:config hacking was a
disclaimer.  I don't know if there are any config hacks to eliminate the need
for that check box or not.  I stated the disclaimer so someone wouldn't chime in
with "Yes you can!  You just edit *this* is about:config".  Got it?  Ok, good.
Again, TB can _ONLY_ do server side body searches.  UNLESS you've enabled off
line mode and have synchronized the IMAP folders.  To "synchronize" in TB
terminology means to download a complete copy of the selected IMAP folders to
the local hard disk.  Once the IMAP folders are on the local hard disk, and you
enable off line mode, any body searches of your IMAP folders will occur on the
local machine.  This isn't difficult to understand is it?

Ok, I'll go with that.  RFC821 headers are indexed but MIME headers are not.
And MIME headers probably shouldn't be anyway, as there would be no benefit
except maybe in extremely rare cases.
