Thanks, that's exactly what I was after. I had partially read Chapter 6
without going on to Chapter 9. There is indeed a reference (which I
overlooked) so if a tweak is ever made to Chapter 6 putting in an
example from Chapter 9 like the above would be great.
I ended up with (in a maildir transport),
directory = ${lookup{$domain}cdb{VMAIL_DATA/popbox_path/popbox_path.cdb}}/${lookup{$local_part}cdb{VMAIL_DATA/popbox/$domain.cdb}}
(better, neater, shorter way of doing this?)
So, I then tripped up in the directors section, naively attempting,
driver = aliasfile
file = ${lookup{_default_}cdb{VMAIL_DATA/forwarder/${domain}.cdb}{$value}fail}
..but found..
driver = smartuser
new_address = ${lookup{_default_}cdb{VMAIL_DATA/forwarder/${domain}.cdb}{$value}fail}
..worked.
What's the rationale behind it working for user = but not file = ? I
might be missing some basic thing here.

Careful, that might end up in someone's .sigs file :-)

OK, will do. I figured spec_6 meant Chapter 6. Yes, I was referring to
all of it scaring me :-)
