This is a comment more than a question.
I don't think Shaw's spam filter is particularly bright. The number of emails that are not spam that get flagged as such and/or put into the Junk folder AND the number of emails that are spam that don't get flagged as such and put into the Junk folder is a bit of a pain.
An example is the subject of this. Shaw marks ITS OWN emails as spam. Talk about irony.
