Sure. But it's a bootstrap paradox, of course - no one supports it because no one is using it, which they can't do till someone supports it ... But with SA 3 not too far away, there's going to be lots and lots of people able to validate it Real Soon Now, so I was thinking it might be able to try it out. This is one of the best things about qpsmtpd, I think - its fantastic for prototyping new ideas and seeing whether they've got any value. > On the outward side... that seems quite out of place for qpsmtpd, > although I could understand if you're using it for relay.
