Rejecting Mail from foreign countrys

[Kiwica]

Hi, recently switched from sendmail to qmail, and using webmin to partially administer spam assassin and other features. The badfrom module says that using the syntax @*.XX in the rejected addresses filed should block mail from that domain. Heres my question, if I wanted to block any emails from New Zealand (.nz) then my understanding is I would enter @*.co.nz or @*.nz but neither of those work, nor does @co.nz, @.co.nz, @nz, @.nz.... Anyone know the correct formula or if in fact qmail can block from a country level??


Thanks
