I do this somewhat differently.
The only requirement is you have a seperate db file for each virtual
domain - I don't have a problem with this, some people do but I think
it is more efficiant and nicer.
(I also break it down to sub directories of the first character of the
domain to be slightly more efficient and so it scales better).
>From my config file:
# does your db implientation require .db at the end of db file names ?
# uncomment whichever you need.
DBEXT = .db
#DBEXT =
# add dbm;/usr/local/etc/exim/dbm/virtualDBEXT to your local_domains
# director:
# deal with virtual domains.
virtual:
driver = aliasfile
domains = dbm;/usr/local/etc/exim/dbm/virtualDBEXT
no_more
rewrite = false
file = /usr/local/etc/exim/domains/${lc:${length_1:${domain}}/${domain}}DBEXT
search_type = dbm*
All you have to do to enable a domain is add it to
/usr/local/etc/exim/dbm/virtual
and make sure the db file in /usr/local/etc/exim/domains exists.
Since the search_type is dbm* if there is a * entry it is used as a default.
I have alias files along the lines of:
foo.pir.net:
*: pir@???
info: fred@???
