Word Filter - multiple words at once

[Dixiesys]

For the word filter in email, it'd be nice if you could dump a whole bunch of words into it at once.

Also a "master list" for a user so they can dump all those words only once, in the case they have multiple domains.

I suggest if this feature could be disabled completely... If it's trying to catch spam, it will more than likely miss it. What is the other purpose of this filter? If used, I'm sure it adds a decent amount of CPU overhead.
