Hi !
Just now my work e-mail accounts attract a silly amount of spam, I'm taking hundreds per day. I can't do anything server side as our hosts are living in the dark ages when it comes to hosting and the boss doesn't want to host ourselves here.
I have tried various ad-on filters, but none are that robust. The Outlook filters are great, they filter all the spam but they also filter most of my good mail to, so it's not very helpful. the nature of my work e-mails mean that no matter what I do a high number of good mails get filtered as junk or spam.
Any ideas or suggestions? Or is this all a bit of a pipe dream?
