And so on.....I'm sure every list >owner has the same experience. All true, but whose fault? It's not LISTSERV's fault that mail daemons generate incorrect or inappropriate error codes. It's *possible* for mail systems to be configured to recognize that hosts may be temporarily unreachable and name servers don't always respond within defined timeout parameters. In fact, coding software to recognize weekends is nearly trivial. If enough users are inconvenienced and directed to the actual source of the problem (often their own host's mail system) then pressure will be exerted to fix the real problems. There still are a (very) few hosts that return error messages to the internal 'from' address instead of the envelope MAIL FROM (ignoring RFC 1123--the mail standard that's been in place since the late 80's). Such misprogrammed and misconfigured mailers used to be common, until their postmasters got tired of having their daemon'sail sent back to them with the request that they forward it properly (and fixed or replaced their mail software). If yo week's Time cover story is worth a glance (yes it's shallow, but it's not bad for mainstream press). The assertion is made that the Internet is growing so fast that it won't be able to sustain existing ways of doing things. That prophesy has a lot more chance of becoming true if sloppy procedures aren't cleaned up. APPLE2-L operates out of BrownVM. Very few of the auto-deleted subscribers have either complained or re-subscribed (okay, the Apple 2 isn't a hot item any more and the list is neither large nor very active, but my experience is that most of the auto-deletes were caused by legitimate 'unknown user' returns). /s Murphy A.
