I can't answer your question, but I don't think it's a good idea to even 
try it like that. That's what the "envelope" test in RFC 5228 is for ...

require "envelope";
if envelope :all :is "from" "tim at example.com" {
                discard;
}

<http://tools.ietf.org/html/rfc5228#section-5.4>

So the better question would be IMO if and when Cyrus will support that 
test.
