Thanks for this, I was in middle of implementing something like this
when I read the post and realized it would work. It did raise a
question for me though. If I'm using the valias with mysql, how
would I enable those accounts to be check for viruses since
vdelivermail would need to be called to have it forward it according
to the mysql table? I can't use a .qmail-<alias> file that sends it
to the script which then sends it to vdelivermail for the reason you
had mentioned.
