This message is a "probe" for your subscription to the FMPRO-L list.
You do not need to take any action to remain subscribed to the list.
Simply discard this message 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 may not see the signature
because it is in the mail headers). If the subscriber's email address
is no longer valid, then the message will be returned to LISTSERV and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, then the message will not bounce and the user
will not be deleted.
