Spamfilter wordlist

[johannes]

The format in /etc/virtual/domain.xy/filter.conf is as this:

0=type=word&value=blockword1
1=type=word&value=blockword2

Is it possible to have a simple wordlist, example

blockword1
blockword2
blockword3

and to push this forward into the filter.conf , but becoming the right filter.conf formatting? Either manually for single domains, or on account or domain creation?
Is there maybe a script which can do this, or a command?

And are the words case-sensitive (eg: spam vs. Spam)?

Thanks!
