Is there a Postfix header check that can reject an email if it contains any emoji in the subject line? I've been getting a bunch of email with green hearts or smileys etc. in the subject line - all spam - but I can't figure out the regex for it to reject it at the Postfix level rather than waiting for Spamassassin to pick it up. thanks.

Work off of this:

Or maybe a milter that runs it through this:

This would be a good filter to add to spamassassin.

100% of mail I get with emoji's in the subject are spam.

I'm almost as certain that this applies to bodies of messages as well.
