Thank you David, Jared and Jari. Adding: Subject:raw =~/=\?utf-8\?B/i Subject =~ /[\xe4-\xe9]/ caused this crap get caught. Both works, so I will keep David's advice. So I think I will just remove this TexCat plugin which does not identify it properly. This is great list, thanks again for everyone. All help appreciated. Jenny
