I use fastforward (http://cr.yp.to/fastforward.html) for this purpose. I
run a cron job (writtin in Perl) that grabs the aliases & forwarding
addresses from a database and opens a pipe to the 'setforward' command to
create the CDB forwarding database. fastforward is written by D.J.
Bernstein (the guy who wrote qmail), so it's very fast/efficient/reliable
(as all of D.J's software seems to be!) My .qmail-default file looks like
this:
| /var/qmail/bin/fastforward -p /location/of/forward.cdb
| /home/vpopmail/bin/vdelivermail '' bounce-no-mailbox
Here's the important part: the -p switch to fastforward tells it to only
forward the message if it finds a matching alias, otherwise it returns the
appropriate error code and qmail will go on to the next line in the -default
file, and attempt to deliver using vdelivermail.
I hope that makes sense or is somehow helpful to you. You could probably do
something similar with your own program--by returning the proper error code
you can change the way qmail handles the rest of the lines in the -default
file.

Subject: A question of defaulting
Ok, so everything seems good. However. Before I
installed vpopmail I had a little C prog that went
into my -default files for my domains and if it found
an entry in the database that matched, returned the
proper alias to forward to. I would like to do that
here as well, but I am not sure how to go about it.
It could go before the vdelivermail but I would
prefer it to run after, I think. Is there some
way to do this?
