Ralph Papakhian" <PAPAKHI@IUBVM> You have been victimized by a common, and IMHO inexcusable, nuisance. A mailer that's out of policy and sending undelivered mail notices to the "From" address instead of to the "Sender" (actually, it should be to the envelope MAIL FROM, but in the case of every LISTSERV list I know of, its the same thing) like it is supposed to. This problem (and its solutions) has been recognized for more than four years. A year or so ago CREN adopted a REQUIREMENT that BITNET nodes conform to RFC 1123 (the Internet standard). A few have not done so. Sometimes the problem is an inadvertent mailer configuration error (some mailers evidently are hostile even to postmasters). More often the host site has an attitude problem (the attitude being "what do I care of I annoy users all over the world, I'm too busy to be bothered with the problem"). In addition to IUBVM, other hosts I've recently noted doing the same thing are GMUVAX, CGC, and MARICOPA. My policy which I *urge on you all* is that because such misconfigured mailers do not bring delivery problems to the attention of list owners, it is NOT APPROPRIATE for such subscribers to receive LISTSERV service. I simply send a DEL listname *.jerkhost every time one of these comes to my attention. Alas, it appears the only way to make the problem personally serious enough to the host postmasters to get them to correct it (we aren't their constituents, but their local users are). /s Murph <[log in to unmask]> BITNET/Internet ...!bitnet!uconnvm!sewall UUCP + Standard disclaimer applies ("The opinions expressed are my own" etc.)
