This is only a wild guess, but possibly there is a "broken" e-mail worm
that is trying to send itself out to a group of harvested addresses
that includes your list's -join or -subscribe address and the headers
in the message it sends are run together without CRLF line breaks or
with leading white space that makes them look like one long header.

It seems that your list already requires approval for new subs, and
probably the best you can do is discard these and not worry about it.
