Using a database for managing virtual users seems overkill, until you
run into issues like this.

I have a postgres backend for 20ish users, and I can plugin everything I
want. Postfixadmin works geat, and there are many password plugins for
squirrelmail/roundcube/etc that work with such a database.

Disclaimer: I tried the file-based approach too, but kept building
kludges for things that were a lot simpler with a database. In the end,
I joined the dark side.
