Have a directory /etc/mail/vdomains/

For every domain which you handle, create a file inside that directory.
In the simple case, a flat aliasfile; for efficiency, look at later
moving to something like .cdb files.

Do _not_ have a normal "localuser" director.

Have something like (untested):

vdomain_accept:
driver = localuser
require_files = /etc/mail/vdomains/$domain
local_parts = lsearch;/etc/mail/vdomains/$domain
transport = your_normal_delivery_transport_here

Read "6.2 An lsearch file is not an item list" in spec.txt, to decide
whether or not you really want that to be an lsearch; if you start with
that, though, then migration to a DB later might be easier.


This may all be completely wrong. When the fine fare of the nearest
Irish pub clears from my mind, I may well regret that example. Test
thoroughly on a non-live system, or at the very least on a port other
than 25. E&OE.
