Virtual Domains in separate directories - how?

[former03 | Baltasar Cevc]

Hi, as far as I know, Web-yradm will always maps an address to
some address @ the server hostname (mailbox at virtual.domain will
become virtual.domain will map to virtual.domain.mailbox1 or
something similar). As cyrus only sees this mapped address, all
mailboxes _are_ in the same domain from its point of view.

Cyrus will automatically separate domains when you really use
a virtual domain setup (where your MTA delivers the message to
cyrus as mailbox at virtual.domain).

Hope that gives a useful starting point,
Baltasar
