Not really - that would mean I have to install SQL just for this one
solution; too much of an overhead. I'd rather use perl I think :-)

The virtual domain user list is a CDB file (created from a plain text file),
but I get your idea. However, as the subject line said, I want it 'dynamic'.
I don't want to manually (or via cron) run a program, I want exim to go get
the info whenever it needs it.

I'm not so concerned about 'expense' so long as it's dynamic. Having said
that I'd like to do this without using other software such as SQL or perl,
which impose their own overhead on the lookup.
Thanks for the ideas though, I'll have to think a bit more.
