LISTSERV AT VM.MARIST DOT EDU has just received the enclosed delivery error as a
result of a probe sent to your ADSM-LIST AT ADSM DOT ORG account for the ADSM-L
list. If you are reading this message, it means that your mail system is
successfully delivering mail to your mailbox, while at the same time
reporting that an error has occurred (or, alternatively, the error could
be due to a system problem which has since then been fixed). At any rate,
LISTSERV has no way to know that you have actually received the present
message, and is operating on the assumption that your e-mail address is
no longer valid. Typically, LISTSERV will send you one or more additional
probe messages, on a daily basis, to determine whether the failure
persists, and if so you will be removed from the list eventually. Some
lists are configured to remove users on the first failure.
Assuming you have not been removed from the list yet, you can stop this
process by sending the following command to LISTSERV AT VM.MARIST DOT EDU as
soon as possible:
CONFIRM ADSM-L
This will tell LISTSERV that your account actually does work and that you
still want to receive mail from the ADSM-L list.
While the CONFIRM command will solve your immediate problem, it is only a
matter of time until you find yourself in the same situation again.
Please take a look at the enclosed error report and try to determine
whether it is a genuine error, or just an informational message. Bear in
mind that this error report was processed by a computer that cannot tell
"User JAIME24 does not exist" from "Please note that the Department of
Microbiology will be closed from December 19 to January 2" or "Attempts
to deliver your message have been unsuccessful for 300 seconds; will keep
trying for another 431700 seconds." These informational messages, while
possibly useful to a human reader, should not be sent in answer to a
message coming from a mailing list (it is very easy for the mail program
to determine whether a message is coming from a mailing list). Genuine
errors should be reported to your computer/network support staff as soon
as possible so that they can be corrected.

This message is a "probe" for your subscription to the ADSM-L list. You
do not need to take any action to remain subscribed to the list, and in
particular you should not reply to this message. Simply discard it now,
or read on if you would like to know more about how this probing
mechanism works.
A "probe" is a message like the one you are reading, sent to an
individual subscriber and tagged with a special signature to uniquely
identify this particular subscriber (you can probably not see the
signature because it is in the mail headers). If the subscriber's e-mail
address is no longer valid, the message will be returned to LISTSERV and
the faulty address will be removed from the list. If the subscriber's
address is still valid, the message will not bounce and the user will not
be deleted.
The main advantage of this technique is that it can be fully automated;
the list owner does not need to read a single delivery error. For a large
or active list, the manpower savings can be tremendous. In fact, some
lists are so large that it is virtually impossible to process delivery
errors manually. Another advantage is that the special, unique signatures
make it possible to accurately process delivery errors that are otherwise
unintelligible, even to an experienced technical person.
The drawback, however, is that this method lacks flexibility and
forgiveness. Since the Internet does not provide a reliable mechanism for
probing an e-mail address without actually delivering a message to the
human recipient, the subscribers need to be inconvenienced with yet
another "junk message." And, unlike a human list owner, LISTSERV follows
a number of simple rules in determining when and whether to terminate a
subscription. In particular, a common problem with automatic probes is
mail gateways that return a delivery error, but do deliver the message
anyway. LISTSERV has no way to know that the message was in fact
delivered, and in most cases the subscriber is not aware of the existence
of these "false" error reports. If this happens to you, LISTSERV will
send you another message with a copy of the delivery error returned by
your mail system, so that you can show it to your technical people.
