One of my email accounts is getting deluged with Spam and as a consequence, I'd like to impose a ban on mail from the country of origin - a Top Level Domain ban, I guess.  This is possible using MS Outlook  - does anything similar exist within The Bat! ?  I'm already using Anti-Spam Sniper (free edition) but it doesn't seem to offer that option in either the free or paid-for versions, as far as I can see.
