Yes, you're right. I just meant that on postfix you can define a static
uid for the virtual(8) delivery agent, and forget all about it when
defining virtual users. I just have a list of valid recipients and
that's it (no mapping).

Sorry, now I'm confused. Do you mean 'foo => foo' is valid even if there
is no local user 'foo'? (and I really apologise for all the newbie
questions).

All I want is to be able to handle multiple domains with multiple
recipients, each with its own maildir, without needing to add a local
user for each one. As I said, I managed to do this easily by mapping
every recipient to a local user, so problem solved :).
I was just wondering if this could be done without having to add '>=
localuser' to each entry of the 'users' table, basically.
Thanks for the patience and sorry for the noise.
