And how exactly does 'hiding' who you are help security as the SMTP client
already knows who they are connected to... this makes no sense at all
for that purpose, I do understand not advertising the exim version, or for
that exim is being used at all in the HELO Banner, not that profiling
cannot find that out any way (or at least a close approximation).
