Which is all a bit of a bitch since you also end up having to handle
MIME - it all adds a pile of complexity to exim since you end up needing
a large chunk of a decent MIME parser if not a complete MIME parser.
At present you *could* do the 8bit -> 7bit conversion in a transport
filter. However the filter would be invoked on every message (I can't
think of a way that the filter could be invoked for just 8 bit messages
and just when the next hop is non 8 bit).
I wonder if its worth spending the time:-
1. Setting a flag of some sort on incoming messages which are
non 7bit clean/
2. Having flags within the SMTP transport based on what the
ESMTP negotiation says - ie whether it does 8 bit etc
3. Having the transport filter conditional and/or parameterisable
based on these flags (ie expand the condition for that very
late in the day - may be like this already).
The only thing that really concerns me then is that the ESMTP size
functions could be completely loused up by a transport filter thats
re-encoding the message.
