I think this is because SpamAssassin is outputting more than 8k of header
(probably some quality spam with a score of 50 or something). Check this,
from the INSTALL file of SA-Exim:

That seems a bit inconclusive; perhaps Marc will tell us if he's figured
out what it is you need to do to get Exim to allow >8k string expansions.
(and if not, perhaps Philip can shed some light...)

I have to say I left it alone, and I don't seem to have hit the 8192 limit
yet, but I guess it's only a matter of time, so I'd like to know too :)
