Subject: Subscription probe for MoPo-L - please ignore
Sun, 9 Mar 2008 06:01:10
This message is a "probe" for your subscription to the MoPo-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address is no longer valid, the message will be returned to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.
