1/ are you sure you didn't invert FROM and TO ?
2/ i'm not sure you understand my question : if I have 3 domains configurated in PMG, how can I add a common blacklist for these 3 domains ? But then each user should modify its own blacklist then.
Thx but this rule exists by default. Or do you mean that when a user add an email address in its own blacklist it adds for everyone ?
And I still don't know how to add my emails addresses list to blacklist.
