Hi,

I'd like to block all senders from .co.ua and bis.ua. A rule like this

racl "BL_UKRAINIA" blacklist from /\.co\.ua$/ msg "Bad reputation - 
sender addr <%f> listed on SPAM blacklist %a" flushaddr

does not work, because of ending bracket ">" in sender addresses. This 
works

racl "BL_UKRAINIA" blacklist from /\.co\.ua>$/ msg "Bad reputation - 
sender addr <%f> listed on SPAM blacklist %a" flushaddr

but is there a way to block ending /co.ua$/ with or without ending 
bracket?

Thanks
Marcus
