Hi,
If I understand what you are trying to achive correctly, you are
after "sender_address_relay" which lists the domains that senders who
relay through your system are allowed to use.
We use a mysql query for this, being:
SELECT DISTINCT Domain FROM Domains WHERE (Domain =
'${quote_mysql::${domain::$sender_address}}')
Though using a lookup in a file would be the same sort of thing, just
have something like the following in a file and do a lsearch on it:
192.168.0.1: domain1.com:domain2.com:domain3.com:blahlbha.com
192.168.0.2: meep.com:wibble.org
Etc... And do an lsearch on it.
Saying that, maybe I didn't understand the question correctly, i've
only just woken up :)
