But then couldn't anyone with a DSL line in Eastern Masschusetts use this
'open' mail relay for spam?

I think what you are saying is that it matches _strings_, and doesn't look
up IP addresses of the hosts defined in the relay list.  That's a problem,
I guess I'll just have to get the DNS updater to Email me and I'll twiddle
the bits by hand (unless anyone knows how to change DNS securely from
outside the RAQ like dyndns.org et al do?).

Thanks!
