Think the filter is dead, just because it's delayed? Think again -- this is a tactic to get 'a clear mandate' at the next election to implement it. "Vote Labor, vote filter."
We just recently added email accounts to our domain and the hoster provides cPanel Pro 1.0 (RC1) for configuring various email/filtering aspects. When I define an account level filter, ~/.cpanel/filter.yaml is created.
This is a topic that usually comes up around election time, but I figured why not start this while I'm thinking about it. Do you vote straight party lines, vote your conscience, always for or against an incumbent, or some other way? And why?
