Please excuse me if this is off topic;  if so, I would appreciate a pointer
to the correct list.

We've received a few thousand late this afternoon of email messages similar
to the below.

What do you make of this?  Is there a defense other than blocking the
alleged IP range?

Your opinion appreciated.

Larry
