IMHO, this is most likely a spoofed subscribe ... it is not a normal list
distribution but a LISTSERV-generated WELCOME message [?].  Thus first
determine how long (if at all) the individual is subscribed.  It you have
appropriate controls on your list e.g., SUBSCRIPTION= OPEN,CONFIRM, then
it probably is a legit subscriber who needs to alert his/her postmaster
of a whitelisted list (as others here have said).
