Fair enough - my virtual local agent hasn't had much review yet, so
I'd suggest keeping a very close eye on it's behaviour, but it gets you
away from the dependancy on /etc/passwd.

Wietse also suggested an alternative - you could use the virtual table
to map the real e-mail addresses to an intermediate form, and then an
alias to map this intermediate form to a file alias. Delivery will be
carried out with the ownership of the alias file, however.

I still think you're going to have to make some modifications to your
popper and imapper - at the very least to remove the dependancy on
/etc/passwd. If they're well coded, the changes will be minor.
