I've read in other threads that the Zonealarm v9 junk mail filter does not work with the Windows Live Mail client.
I beleive that the two clients supported by Zonealarm for junk filtering are Outlook Express and Windows Mail, neither of which can be downloaded for use in Windows 7.
Although technically Windows 7 does not come with an email client, Windows Live Mail is the client recommended by Microsoft and is the "logical" successor to Windows Mail and Outlook Express. Millions of users across the world will be shifting to Live Mail.
So Zonealarm, how do I use the junk filtering function in an email client on Windows 7? Surely you must be working on supporting Live Mail, mustn't you? When will it be ready?
