Does this just return an "accept code" or something back to Exim? Will any
external executable do the job (ie. I know Perl quite well, but little C)?
Would it be possible for whatever Perl code I write to handle all of the
external checking on email contents looking for spam by Exim calling out
to it and returning an 'X-' header with the process to follow?
Thanks very much for the advice!
