Yes, although I had to go back and look to see that they were being sent, as I've never actually seen one arrive in a mailbox.

Almost all of them have HELO=localhost, and also fail SPF checks.  The few that get through have high spam scores, and generally come from clueless ISPs like 123reg.co.uk (part of Pipex), who are under increasing pressure to sort themselves out.
