No it won't.  davem has put protection against such mail loops into
this version of majordomo.  Its a real shame that people are so stupid
that they try this.

  It just generates looped messages that are bounced to the list owner.
  Subscriber's message had these headers:  (yes, we do log EVERYTHING
  sent to Majordomo.. We don't log everything sent to the lists, though.
  There are a number of archives for that.)

Could these DoS attempts get filtered somehow?

  Sorry, its me talking "majordomo" -- when a filter is triggered,
  a "BOUNCE" is sent to the listowner(s) for their analysis and decission.

  So yes, they are filtered already by way of a loop filter we have
  introduced, because every now and then people use MTA/MUA softwares
  that make a mistake at receiving a message and consider visible
  "To:" and "Cc:" headers to carry relevant data for message routing..

  Think a bit of this message; "To:" says  "linux-kernel@vger", but
  it will nevertheless be sent to thousands of recipients whose
  addresses are not visible in these headers at all.
  The Internet Email is routed and transported by SMTP-envelope data,
  which in normal cases is not displayed in visible headers.
  Things in these visible headers have at most incidental relationship
  with actual message routing and destinations.

Come on, if Ryan Cumming wants to make an ass out of himself,

It might be an innocent fat-finger problem... I use a digestifying
mailing list gateway to get lkml and almost comitted this error
myself...

Not since whoever did it replied to the confirmation email with the 
proper authorization message.  Definitely intentional.
