My hosting provider filters spam pretty well (I'm using BIS), but for some reason, some still get through but the subject line is prepended with '[SPAM]'. So, I just use the filter feature in my BIS login and block anything with that in the subject line. It seems to work well. I still get the email in my outlook on my desktop computer, but not on my BB.
I also do this with automated messages from myspace and forum sites that don't have a corresponding WAP site (unlike this fine site
). While this isn't junk mail, I don't care if someone has posted something in a forum when I can't read it on my BB.
Oh, it also fixes that little gmail problem too
