Hi All, I was wondering if anyone has ever run into this problem. It looks like I have everything setup properly. I followed a howto that I believe was written by falko for fedora 12 postfix courier-imap amavisd spamassasin. I started by trying to use a self signed cert but obviously outlook 2007 and other email clients complained about not being able to trust the certificate. So I looked into buying a rapidssl certificate. Apparently I can use a rapidssl certificate for postifx BUT now outlook 2007 tells me "All of the intended purposes of this certificate could not be verified" has anyone ever seen this error? I have been trying to get this cert issues resolved for a week now and its drivingme crazy ! I just want to be able to put this new email server into production without having to worry about my customer's getting annoying error messages in their email clients. if anyone can help me with this it would be grately apreciated!!!!
