All my email I need to read is being tagged as junk with 

[Shaw Suspected Junk Email] 

Yet the Junk mail does not get tagged with it. I have been in touch with Shaw several times and supplied them with a list of domains that are NOT JUNK and also had the email address marked as NOT JUNK in the preferences area/ Yes Shaw still considers this junk. I am losing lots of business e-mails as a result. How can we make this stop?
