Okay, now that's different. This actually clicks in very well with the recent article I wrote on fighting spam for publication on the LOPSA website, because backscatter has become one of my biggest hot buttons lately. Putting an intelligent limiter on the potential causes of backscatter (like no more than one notice per recipient per day, or whatever), brings it down into the realm of what I would consider to be less than ideal but at least below the threshold of "totally unacceptable".

Ok, I just checked this 5-minute fix into SubEtha. Happier, Ian?

Yes, that's great! I'd guess that this is 90-99% improvement. In fact, I'd probably use that feature for my local domain (sussex.ac.uk), which is virtually spam free because I only accept from that domain if it's been authenticated, or locally submitted, or has a header that was added by our MSA servers. In fact, the only spam I get into my "local" mailbox is Mailman moderation requests.

I'd still want to reject at SMTP time for non-local domains, though.
