I seem to recall giving out a query about that in the IRC channel a
while back...so if you got it from me, now I'll attempt to finish the
job :-).
If you can get postfix to look at a view, maybe you could
CREATE VIEW email_v AS
SELECT
usr_email, dom_name,
b.dom_name||'/'||a.usr_email||'/inbox' AS email_file
FROM users a, domains b
WHERE
a.usr_dom_id=b.dom_id;
AND a.usr_email='mkelly'
AND b.dom_name='test.com';
and just
select * from email_v where usr_email = 'mkelly' and dom_name = 'test.com';
