Thanks for your help Mark.

You were right about the 'connection refused' error.  I couldn't telnet 
to my localhost on port 25 as we have a mail virus scanner on that port, 
which I'd forgotten about, which needed a bit of messing around with.   
Now I get replies from mailman.

Alas, I still cannot post to the list I'd created.  I think I' getting 
there though.  I try to use mailing lists and usenet as a last resort 
and try to figure these things out for myself.  I prefer being pointed 
in the right direction.

Thanks again
