On Friday, a well known spammer had forged some mails with a return address of a small school machine I still run. It has almost stock qmail, so there's no way to refuse addresses to invalid local users. Also I can't shut it down, since other MX hosts run the same qmail, for the whole school. Fortunately this qmail has a single patch which allows to refuse any specific addresses. After a few scripts to collect all the invalid addresses, and make them into a refuse list, it started to get more manageable. It was 251 invalid local addresses, and more than 5MB of spewage later when it occurred to me that almost all the spam returns are coming from open relay hosts, so I'm back to using rblsmtpd with outputs.orbz.org. About 250 open relays. Without these, SPAM would not be so prevalent. I hate incompetent operators. Including local ISPs who think relay block lists are an inconvenience item to force them changing addresses daily.
