1. Introduction
Maintaining large mailing lists, especially the processing of error
reports, poses many problems. Most of the examples come from the
experience of managing the Internet Engineering Task Force (IETF)
mailing list. Many examples are presented in this memo. Most of the
specific problems shown have already been corrected.
2. Discussion
At USC - Information Sciences Institute (ISI) we maintain mailing
lists for the Internet Research Groups, the IETF, and other Internet
groups; about 25 lists altogether. We receive about 400 messages a
month requesting additions or deletions to these lists. There are
Westine & Postel [Page 1]
RFC 1211 Problems with Mailing Lists March 1991
about 20 messages a day requesting changes to the lists.
We also receive about 300 error messages a month due to mail delivery
problems. Many of these are duplicates, but the net result is that
about 10 cases per day need to be investigated.
Many of the error reports are for "soft errors", primarily delayed
delivery notices, such as "not delivered for 2 days, will try for 3
more days". These just waste the list maintainer's time and are
otherwise ignored. This is especially wasteful when such messages
are repeated every day. However, if the same host is a cause of such
messages for many days in a row, the list maintainer may investigate.
Please note that ignoring the soft errors is not always easy, since
error messages often contain error reports on several mailboxes,
requiring the error message to be read carefully to pick out the hard
errors.
The error reports that indicate hard errors, such as "no such user"
require the list maintainer to take action. In many cases the
appropriate action is to simply delete the user mailbox from the
list. However, if the mailbox in question is someone known to be
active as a working group chair, or such, further investigation is
necessary. The more general case of "no such host" may be a
temporary condition, but if it continues for several days it must be
investigated.
Since the error conditions do not have standardized names (for
example, "no such user" vs. "user unknown") it is sometimes difficult
to understand whether a soft or hard error is being reported, and
what one should do about it. For example, what does "Can't Find Mail
Center!" mean, or what should one do about "mailll:%MAIL-E-OPENOUT,
error opening SYS$USER2:[STGEORGE.LONGMAIL]MAIL$00040093BE236612.MAI;
as outputI)"?
The first step in investigating a problem with a user mailbox is to
see if it is on the list. If so, the next step is to see if there
really is a problem with it. This is done by using the SMTP VRFY and
EXPN features, Finger, or Whois. This often develops information
suggesting that the user has recently changed his address. This has
to be confirmed through an exchange of messages (with the postmaster)
and then the mailing list must be updated.
If the user is not on the list, then it is likely the mail is sent
via an exploder or sublist. So the investigation focuses on finding
which exploder may be involved, usually this is found by looking at
the path (from the received lines) of the error report. The exploder
that is the source of the error can sometimes be checked using the
Westine & Postel [Page 2]
RFC 1211 Problems with Mailing Lists March 1991
SMTP EXPN feature. Then the postmaster is notified.
If the error report is about a host being unknown, the programs
"whathost", "dig", "ping", and "traceroute" may be used to find the
problem. However, getting the problem fixed may require
communication with host and domain administrators.
What to do if problems can't be resolved: Delete the offending entry
from the list that may eventually cause the following response: "I
used to be on the ietf list, how come I am not getting the messages
any more?" (See Appendix A.)
3. Typical Problems
In this section we discuss typical and frequent problems that occur
with large mailing lists.
3.1 Misdirected Error Reports
The most frequent problem is that error reports are sent to the
author of the message rather than the list owner. One way this can
happen is when there is trouble with the author's host not connecting
to another host along the route before it reaches ISI where the
mailing list is.
At ISI the SMTP "from" information is added when the message is
distributed to the list so that hosts following the SMTP protocol
will send their error reports to the list owner. However, not all
hosts do this properly.
Another problem is that some machines do not pay attention to the
SMTP information about where to send error reports.
3.2 Sublists
What is a sublist? It is a mailbox with an alias-name that expands
to a mailing-list or group of recipients. There are many sublists on
our mailing lists.
When a user requests that a mailbox be added to a list that looks
like an exploder, the following message is sent:
We ask that all list maintainters of exploder mailboxes (an
alias-name that expands to a mailing-list or group of recipients)
set up some sort of ownership at their site, for their list. What
this means is, is any mailbox on your list is invalid, the error
message will go to you (the list owner), and you can delete that
mailbox from your list.
Westine & Postel [Page 3]
RFC 1211 Problems with Mailing Lists March 1991
An example of an entry in your aliases file would be:
owner-ietf-local: stev@vax.ftp.com,
(or your list maintainer/postmaster)
It appears that few people understand the concept of list ownership,
or they do not set it up correctly. There is ample evidence of
problems in this area.
When investigating "user unknown" messages it is often the case that
the user is not individually listed on our list. The next step is to
check received lines and hunt for an exploder list with a host
similar to the one that the error came from or points to. At that
point we attempt to use SMTP EXPN or VRFY to check that the user is
on a sublist. Since many hosts do not implement EXPN or VRFY, the
result of our check is inconclusive. We then contact the list
maintainer and ask him to delete the invalid mailbox if it is on his
sublist.
Another problem occurs when someone on a sublist wants to change the
name of his mailbox. We look through the main list to make the
correction and if that mailbox is not on the list we check the
received lines and look for clues to determine which host this user
may be on. More than likely it is a sublist. (See Appendix B.)
When the mailbox is in another protocol world (like UUCP or BITNET)
there are often problems with the handling and direction of error
reports. (See Appendix C.)
Sometimes we are unable to find the addresses reported in the error
message on the mailing list in question. In such a case we check the
mailing list for a host name also named in the received lines of a
message in error. If we find a match then we look for an exploder on
that host and expand the sublist there to see if the mailbox in
question is on that sublist. (See Appendix D.)
At the time a sublist is entered into our list we record the name of
the requestor and consider him the sublist owner. As people change
roles or companies this contact sometimes fails, in that case we fall
back to contacting the postmaster. However, not every site has a
"postmaster" mailbox. (See Appendix E.)
Most users send their requests and changes to the IETF-Request
mailbox, when they are on, in fact, a sublist, usually at their own
company. This creates a problem for us trying to determine which
exploder they're on.
Westine & Postel [Page 4]
RFC 1211 Problems with Mailing Lists March 1991
In this case, the request message is forwarded to the sublist owner
so he can make changes to his list. However, sometimes hosts may be
somewhat similar in name (from the same organization, but in a
different department, in a different building, off campus, etc.) and
it's hard to know if this person should really be on that particular
sublist, or listed individually. Occasionally, we examine the main
file to see if there are individual addresses that could be
incorporated in a sublist.
3.3 Misdirected Requests
Some users don't know that mailing lists usually have a "request"
mailbox, so they mistakenly send their requests to the main list.
When this happens, several people will resend the request to the list
maintainer and then want to know if the request was completed.
3.4 Misdirected Messages
There are also messages that go to the request mailbox when they are
intended for the main list. These messages get forwarded to the main
list and a message is sent to the user notifying him of the
correction and the proper way to address his message.
4. Summary
Running a mailing list should be easy, and with small lists it is.
The number of changes and errors are small and infrequent. But when
lists get large and traffic gets heavy, the number of changes and
errors grow to many a day. The level of effort to manage a mailing
list of substantial size and use becomes significant.
An additional problem is the creativity shown by mail program
developers in inventing numerous different error reports. We present
a large sample of such messages in Appendix F. We hope that these
examples will be of help to other mailing list maintainers.
Our experience with maintaining large lists suggests the following:
Users: Please be considerate and try to work problems out locally.
Sublist owners: Please do everything you can to get the error
messages related to your sublist to go to you. Please try to get
users on your system to talk to you about additions and deletions.

APPENDIX B
In this example, the old mailbox "kent@ssbell.IMD.Sterling.COM" was to
be deleted and the new mailbox "kent@sparky.IMD.Sterling.COM" was to
be added. However, when checking the mailing list the old address was
not found. Further checking for anything that resembled the hostname
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
"post-ietf@UUNET.UU.NET". 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.

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.

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-
interest@vitalink.com". 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.

Hello
On our site, the bind@gipsi.fr, snmp@gipsi.fr, ietf@gipsi.fr and the
nameddroppers@gipsi.fr mailed only one person: prindevi@gipsi.fr but
this person has leaved our company, and you should cancel this
addresses.
I think we get enough informations through the news. I think you
should cancel us (ietf@Gipsi.FR) on the mailing list ietf.

F.5. Sublists without local ownership
In this error message there was not much to go on except the
words IETF and the name of the host from where the mailer-daemon
sent the error. Using that clue the mailing list was searched for
that host name (SATURN). It was a sublist. It appears that there is
something internally wrong with the sublist and this error should
have gone to the postmaster or owner of the IETF@SATURN.ACC.COM list
instead of the IETF owner. A message was sent to the postmaster. No
reply was received, but the condition was fixed.

postmaster or list maintainer. They are asked to delete the
invalid user mailbox from their local list.

This is a case where the recipient was checking to see if his mailbox

Hi Stewart and Postmaster,
I readded your name to the IETF list but there seems to be problems
with connections to DECnet hosts right now. I have seen lots of
errors like this lately. Postmaster, please check into this. JANUS
is not the only host with an error, there are other hosts like this
in trouble.

...means that the person on ERLANG:: has forwarded their mail to a
system that ERLANG does not know about. Decnet mail is not store-and-
forward, so decwrl (as smtp-to-decnet gateway) sees the end-system

My advice is to delete any addresses you have trouble with, if they are
in the .enet.dec.com subdomain.

I think I have found out what is wrong. For some reason (we can
discuss this below) your exploder is sending IETF mail to our
exploder (ietf@osi3.ncsl.nist.gov) through the machine
osi.ncsl.nist.gov. Now due to a recent subnet reconfiguration and
subsequent lack of update to our DNS servers, the DNS was returning
an incorrect address for osi3. Thus IETF mail would be sent to OSI,
which would try to forward it to OSI3 (using the wrong address).
OSI would think that OSI3 was down and dump the message, trying to
send a notice to Postmaster. OSI doesn't have an aliase for
Postmaster and thus the second error message that you saw.

These two problems have been fixed on OSI. Now the question is what
address you have in your distribution list that would cause this
mail to go through OSI in the first place. I guess you might have
something like "ietf%osi3@osi.ncsl.nist.gov." The other interesting
point about your list is that we receive IETF mail to our exploder
directly from venera.
Thus I suspect that there are two entries for OSI3 on your
distribution list. One that gets relayed through OSI and one that
points directly to OSI3. If this is the case please deleted
everything except the "ietf@osi3.ncsl.nist.gov." address.
If this is not the case or if there are other problems let me know.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
g. My Reply Back
Here are all the addresses I have on the IETF list under NIST.GOV.
ietf@OSI3.NCSL.NIST.GOV,
mills@OSI.NCSL.NIST.GOV
I'll deleted "mills@osi.ncsl.nist.gov".
Here are two others at NIST
hunt@ENH.NIST.GOV,
sting@CAM.NIST.GOV
By the way, on the following message, it looks like the Mailer-Daemon
message went from OSI.ncsl.nist.gov to enh.nist.gov to venera.isi.edu.

h. Another Problem .Forward
From: Doug Montgomery <dougm@warthog.ncsl.nist.gov>
Organization: National Institute of Standards and Technology (NIST)
To: westine@ISI.EDU
Subject: Re: 421 osi3:Host osi3 is down 550 Postmaster.. User unknown
Deleting the mills@osi.ncsl.nist.gov entry should fix your problems.
Mills has a .forward to osi3, thus explaining why IETF mail was going
---> OSI ---> OSI3.
I checked OSI's sendmail.cf and it is relaying through enh. This,
though has nothing to do with the previous problem.
I flushed the queue of IETF mail on OSI waiting to go to OSI3. I
don't think you should see anymore bounced messages.
Sorry that our local problems were causing you grief .... let me know
if it happens again.

Fifth time now(?) I try this every couple of months now,
figuring you may be hoplesslly backed up.
Can you remove me from the ietf list? I may be there as
either:
fischer@math.ufl.edu
or
netadm@math.ufl.edu
I would appreciate a confirmation message: I'm ready to use
crontab for these mailings.
Many Thanks,
Randy Fischer

Hi Randy,
I remember your request, and I also remember telling you that you are
not on our list (at least individually). There is an exploder
"netadm@MATH.UFL.EDU" maintained at UFL.EDU. You need to check with
the postmaster to see if you are on their list. If this is not the
case, here are the only other addresses I have from UFL.EDU

esj@UFL.EDU,
FCLA@NERVM.NERDC.UFL.EDU,
netadm@MATH.UFL.EDU,
POKE@NERVM.NERDC.UFL.EDU,
There is another possibility, perhaps you have a pointer to a mailbox
somewhere else?
Regards,
Ann

Subject: re: done at last: please release me, let me go...
Many, many thanks for the reply: I did not, somehow, see your
previous reply -- perhaps you forwarded it to someone at UFL.EDU
instead of MATH.UFL.EDU? Or I missed it in the flow of mail I am
trying to abate.
No matter.
At any rate "netadm@math.ufl.edu" is indeed a local exploder, aliased
at the moment to myself and one of my assistants. It is local to the
"math.ufl.edu" subdomain, and not to "ufl.edu" as your records
indicate. I am the postmaster of the "math.ufl.edu", and you should
be able to verify "math.ufl.edu" has an MX record pointing to
"mathlab.math.ufl.edu". I am therefore mailing to you as root from
that machine.
Please remove "netadm@math.ufl.edu" from your list. I have quite
enjoyed the discussions, but the volume been overwhelming.
Thanks very much for your prompt reply,
Appreciatively,
-Randy Fischer <root@math.ufl.edu> <fischer@math.ufl.edu>

Hi Raj,
I will readd you to the IETF list. However, if I receive more error
messages like this, then I must take your name off the list again.
I've sent messages to the postmaster at DEC but the problem isn't
corrected. Your address isn't the only one, there's CALLON and a few
others.

The error message that you sent is unfortunately my mistake and has
nothing to do with DECWRL. One day I reset protection on all my files
and directories and didn't realize that even the system did not have
the privilege to write mail messages on my disk. I discovered it only
after several people sent phone messages to me. Thanks for adding my
name again. I will try to be careful. -Raj

Hi -
Could I be added to the ietf distribution list (again). I must have
been dropped from the list somehow. This happened to me before the
last ietf - I had to get my name reregistered then, too.

Hi Paul,
Every couple of months I have lots of error messags from several
individual mailboxes on ENET.DEC.COM. Here is a typical one. Since
I cannot reach you I am forced to delete your mailbox.
I have sent several messages to the postmaster at DEC but nothing has
been corrected. Perhaps you can look into this.

Hi Ann,
Could we try another address for me? The old address has been
plagued by disk problems which might explain why the mail is not
getting delivered.
The new address to register is:
ciarfella@quiver.enet.dec.com
I will check into the problem on this end. Sorry about the tone of
my first message but this has been a never-ending problem for over 8
months.
Thank you,
Paul C
