I asked my web host company recently why there was no way to block Cyrillic spam – that is, spam email that uses Cyrillic characters in the subject line.
They said there was no way to block those msgs without also blocking legitimate email.
They use different alphabets. I don’t read any language that uses the Cyrillic alphabet, so why can’t I just have a spam filter that sees the character set being used is Cyrillic and automatically chucks it out the door.
How is that hard?
