Excellent. Can this `environment' option be used in user's .forward
(filter) files, or only in the Exim config file?
BTW, here is how I'm using it to add Postfix equivalent $EXTENSION and
$RECIPIENT variables to the environment:
address_pipe:
driver = pipe
return_fail_output
environment = EXTENSION=${sg{$local_part_suffix}{(^\\-|\\+)}{}}:\
RECIPIENT=$local_part$local_part_suffix@$domain
Since $local_part_suffix includes the suffix character (usually `+' or
`-'), I had to remove it. If you end up adding additional environment
variables, a nice one would be a representation of $local_part_suffix
but without the leading suffix character. This is how Postfix's
$EXTENSION and qmail's $EXT work.

That's a nice change of pace. Many MTA authors/maintainers are
anything but.
