FIlter Email on SUbject with UTF-8 data in subject or address

I'm getting a lot of e-mails that contain binary data in the subject such as ( Subject: =?UTF-8?B?bWljcm9zY29waWMgw75hcnRpY2xlIHRlcm1pbmF0ZXMgaGVycGVz?= ) when looking at the raw data. I've seen similar coding in the address field and can't trap those either.

I'm trying to filter these out but can't seem to fined a way to do that. Obviously this encodes the actual subject which would be "microscopic þarticle terminates herpes" but can't filter on the words in the subject.

How can I trap messages like this?

Thanks
