[exim] Full SMTP session log functionality

Hello,

is there any reason not to place full SMTP session record in exim log?
Exim write to stdout such informations (marked with SMTP>> and SMTP<<)
while it is running in debug mode (-d+receive), but it would be nice to
see it in regular log, because often, more easily is to analyse raw SMTP
dialog to see what happend and what is wrong with service. Is there
planned such functionality in exim? It should not be difficult to implement.

Regards.
