Still broken; I disabled IPv6 in my cf's, and sendmail doesn't even try
to listen on IPv6 now when I restart it.
I don't think it did anyway before, it was just trying to but I don't
have IPv6 in my stack since I disable it in the kernel config, so it
just ignored ipv6 after startup.

I think something else is going on. The weird thing is that it's just
certain mail hosts that it's rejecting.
