    yeah but spammers are getting snaky they are latching on to other real domains I may not want to block a real for sale site, like @gumtree. com, yet I get spam frem @tyrgfs.gumtree.com the filter wont let me use the two full stops!

    and If I try to block @gumtree I loose my notifications and still get all the spam!
