You're correct. Technically, we get this wrong. It's one of those things that ... well, our address parser is kind of a complicated mess. But we DO have some code that claims to fix those kind of things up and quote them properly, but I don't think it works for all cases, and I suspect this is one of them. And, if we're being pedantic about it, technically no compliant MUA should be GENERATING those messages today. So, there's not an easy solution. --Ken
