Yes. Irrelevant. I'm asking about spamd's behavior. Not the sender's. > Just use your MTA's built-in features. One can do EVERYTHING spamd does with the MTA ... It seems that that's what *you* would like to do. Great. That's neither (a) what i'm interested in, nor (b) what I'm asking about. So, *do* you know what, if any, values 0 <= x < 1 are allowed by spamd code? If not, thanks for your input :-)
