Has anybody been able to stop emailed newsletters from a particular source being treated as spam by addinding the senders email address to their whitelist? I'm getting very close to turning of spam protection. Since the switch to Cloudmark it's gone completely downhill!
I raised a ticket about the latest occurrence. The response was that I had the wrong thing whitelisted as the email envelope-from was different to the from address. I'd looked at the headers and hadn't realised the issue - how on earth a normal user is supposed to work out what should be added to their whitelist I don't know. I suspect most wouldn't even know about the headers and how to view them. To me it looks like a tool is needed which analyses an email and tells the user what needs adding to their whitelist.
