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.
Check the DNS forward and reverse of the rejected hosts. It may be a DNS
issue.
