"Reverse" Reverse Access.db
I have been looking for a way to run a 'reverse' access.db
Instead of filling access.db with spammers I would like to do the opposite
I want to DENY all email expect those in a list file.
I don't want to 'firewall' anything (no IP chains etc..).
Preferably some kind of rule set or change that would reject all email except those addresses in a file
Is this possible without rewriting the entire cf file?
Is there a "deny-all except these" aspect to the access file?
