My Exim box is a front end filter for 10 domains using different mail
servers (Exchange, cPanel, ClarkConnect & Groupwise). Dictionary attacks
are taking their toll on the filter, so I would like to build a
recipient list into the filter. Three of the domains are getting most of
the spam. What I envision is a text file like this:
Where the domains getting all the spam have a recipient list that is
kept up to date, rest of the domains will accept and forward all clean
mail. Any ideas?
