I'll answer for Manfred or Silvia since both are on vacation for the next couple of weeks. This is certainly my point of view and is not approved in any way. 1. The DFN-office in Berlin is responsible for this mass mail. The postmaster is Gabriele von Siebert, [log in to unmask] Please send any comments to this address. It's useless to complain on lstown-l or lstsrv-l. 2. Currently it doesn't matter whether you send mail to a dbp.de or a d400.de mailbox, because both are considered identical as seen from BITNET or the Internet. The gateways translate the address internally to admd=dbp or admd=d400 depending on which admd is supported by the destination site. Outgoing X.400 mail to BITNET (and Internet) is always sent with an origin of d400.de. Personally I agree with Eric and Christian in that it is probably in the users' own interest to remove all dbp.de addresses globally and ask the users to resubscribe. It is my understanding that the DFN-office intents to drop support of dbp.de by the end of the year, so they will be deleted anyway sooner or later. "Sooner" is preferable, since as long as dbp.de is valid, the notification messages will be delivered. 3. The headers were most probably garbled, because sendmail didn't like 500 recipients listed in the To:-field. I'm pretty sure these mails left DEARN intact, but since I don't know how the mail arrived in your mailbox, I can't be more specific. I'm sure I don't have to tell lst*-l subscribers about better ways to send large distribution mails. :-) Regards, rr
