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no longer valid.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.
