still did not turn up anything.  Then checking the full header
information of the sender's message showed that the message came
through UUNET.UU.NET.  There is a sublist on UUNET called
"[e-mail]".  By using the SMTP feature EXPN on the
sublist the mailbox was found in the form "ssbell!kent".  Finally, a
message was sent to the postmaster at UUNET and asked him to delete
the mailbox.

   Hello,

   I am currently receiving ietf related email at
   [e-mail].  I am moving to sparky.IMD.Sterling.COM
   as the ssbell system is going away.  Could you please change my
   address to [e-mail] so that I can stay on the
   list ? Thanks.

   Hi,

   Please delete the mailbox ssbell!kent from the "post-ietf" list.  I
   will add his new address "[e-mail]" directly to
   the ietf list.  Thanks. Ann

RFC 1211              Problems with Mailing Lists             March 1991


                              APPENDIX C

Another problem comes up when a sublist happens to be located in another
protocol world such as BITNET or UUCP and that mail is forwarded through
a mail relay.  Experience shows that proper implementation of the list
ownership concept is even less likely.

SIGNET is a host in the UUCP world receiving mail forwarded through
the mail relay THINK.COM.

   Hi,

   We have a mailbox on the ietf list that gets relayed through your
   host THINK.COM. We will have to delete this mailbox if a connection
   cannot be corrected.   Thanks, Ann

RFC 1211              Problems with Mailing Lists             March 1991


                               APPENDIX D

Sometimes, the addresses reported in error can't be found on the IETF
list.  In this example, "GATORCORP" is not on the IETF list.  In
checking the received lines there is a host called VITALINK.COM.  We
have an exploder on our list at VITALINK called "ietf-
[e-mail]".  The program DIG shows that VITALINK.COM MXs to
UUNET.UU.NET.  Since VITALINK is not directly on the Internet the EXPN
and VRFY features of SMTP don't apply, the sublist on VITALINK can't be
checked.  However, there are enough clues to make an educated guess that
the mailboxes on the host GATORCORP are on the exploder sublist at
VITALINK.  In this situation a message was sent to the Postmaster of
VITALINK.COM to ask him to delete the invalid addresses from his
sublist.

   Hi,

   We have an exploder mailbox on the IETF list called
   "[e-mail]".  I'm not sure, but I think the
   following addresses may be on that list.  Please look into this
   "host unknown" problem.  If these addresses need to be deleted,
   please do so.

   Thanks,
   Ann

                               APPENDIX E

Every host on the Internet that processes mail is required to have a
"postmaster" mailbox to receive error reports and trouble inquiries.
In this case, the "postmaster" mailbox was not recognized.
