Since nobody now runs ident servers, there will be no reply, and my server waits for a timeout of thirty seconds before continuing. All legitimate mail servers will wait that long, spambots won't. But a failure by these mechanisms would be reasonably repeatable. My server has occasionally rejected Debian list posts for lack of DNS information, presumably when the DNS server is very busy. This is not repeatable, and is quite rare. It never happens multiple times, so my score never gets anywhere near unsubscription. I was once kicked off because my phone line died for several days. I'm not sure a temporary server failure is a good reason for unsubscribing someone. -- Joe
